Introduction

Up and Running Overview

Introduction

The QUESTemp° 44 and QUESTemp° 46, offer traditional heat stress monitoring without the
aggravation of maintaining a wet bulb. Through collaboration with Professor Dr. Thomas
Bernard, from the College of Public Health at the University of South Florida, mathematical
models were implemented to create a Waterless Wet Bulb calculation through a combination of
dry bulb temperature, globe temperature, relative humidity, and air flow. The Waterless Wet Bulb
is used to calculate the Wet Bulb Globe Temperature (WBGT) which is a widely-used method to
monitor environmental conditions related to heat stress.

QUESTemp° Models

Figure 1-1: QUESTemp° 44/46 Heat Stress Monitor

QUESTemp° 44 and QUESTemp° 46 both measure and calculate the dry bulb, wet bulb, globe,
WBGT indoors, WBGT outdoors, relative humidity, and Heat Index or Humidex.

With the QUESTemp° 46, you have the capability to measure stay times in order to manage
work/rest regimens. Guidance is based on the screening criteria for heat stress as defined in the
ACHIH TLV Handbook, U.S. Navy PHEL charts, U.S. Navy/Marine Corp. Ashore Flag system,
and EPRI Action Limits.

An additional feature with the QUESTemp° 46 is an optional detachable probe for measuring air
velocity to determine appropriate levels of indoor thermal comfort monitoring.

Placing the QUESTemp° 44/46 on the Job Site

The QUESTemp° 44/46 should be placed at a height of 3.5 feet (1.1 m) for standing individuals
or 2 feet (.6 m) for seated individuals. Tripod mounting is recommended to get the unit away from
anything that might block radiant heat or air flow. A 1/4" x 20 threaded bushing on the bottom of
the instrument allows mounting to a standard photographic tripod. DO NOT stand close to the
unit during sampling.

Before data logging, allow ten minutes for the sensors readings to stabilize.

About the Sensor Bar

Sensors

About the Sensor Bar

The sensor bar, on the QTº 44/46, is calibrated to its specific instrument and is not
interchangeable with other QTº 44/46 products. The instrument has a sensor bar label which

includes the serial number of the instrument and a sensor bar number. (This is indicated in the
diagram below.)

Globe Thermometer

The globe thermometer (left position) gives an indication of the radiant heat exposure on an
individual due to either direct sunlight or hot objects in the environment. This is accomplished by
placing a temperature sensor inside a blackened copper sphere and measuring the temperature
rise. The WBGT index is based on the response of a 6-inch diameter globe. The QUESTemp
uses a 2-inch diameter globe for a faster response time. The temperature of the 2-inch globe is
correlated to match that of a 6-inch globe.

Figure 1-4: About sensor bar and serial number

Waterless Wetbulb Sensor and Relative Humidity Sensor

The relative humidity sensor (middle position) is used to calculate the Waterless Wetbulb from a
combination of dry bulb temperature, humidity and wind speed measurements. The Waterless
Wetbulb is used to calculate an estimated WBGT value.

Sensors

Dry Bulb Thermometer

Dry Bulb Thermometer

The dry bulb thermometer (right position) measures the ambient air temperature. This
measurement is used in the outdoor WBGT calculation when a high solar radiant heat load may
be present. The series of white plates surrounding the sensor shield it from radiant heat.

Remote Sensors

Tri-sensor Weighted Average

Remote, Sensors 2 and 3

The top sensor bar (sensor 1) may be removed from the instrument and used through a remote
cable. Shelter the instrument and remote the sensor bar if the measured environment is
expecting heavy rain or if temperatures are above 60°C.

The sensor 2 and sensor 3 jacks on the side of the instrument allow simultaneous monitoring of
up to three sensor arrays using connecting cables.

Cable lengths of up to two hundred feet (61 meters) may be used without a decrease in accuracy
provided the environment does not contain strong electromagnetic fields.

The data from these arrays may be viewed separately or combined into a weighted average
WBGT reading per ISO 7243. Change the displayed sensor bar by pressing and releasing the
enter key. The upper right corner of the display shows the current sensor bar. 1 refers to the top
sensor bar, 2 and 3 are labeled on the side of the unit, W indicates the weighted average which
only appears if a WBGT is displayed and all three of the sensor bars are attached.

Tri-sensor Weighted Average

Per the recommendations outlined in ISO 7243:2017, when the temperature in the space
surrounding a worker is not uniform, it is necessary to determine the WBGT index at three
heights corresponding to the worker's ankles, abdomen and head and perform a weighted
average on those values. It is computed using the formula:

The QUESTemp° 44/46 always assigns the top sensor bar the double weighting. This calculation
is shown if a WBGT display has been selected and if three sensor sets are connected.

Measurements

Waterless Wetbulb

Measurements

The QUESTemp° 44/46 data logging area heat stress monitor directly senses three parameters:
dry bulb temperature (DB), globe temperature (G), and relative humidity (RH).

It computes the wet bulb (WB), the Wet Bulb Globe Temperature (WBGT), stay times for four
possible indices, and the Heat Index (HI) or the Canadian Humidex. Using inputs on the side of
the instrument, two additional sensor arrays can monitor up to three locations simultaneously.

On the QUESTemp° 46 model, you can measure air flow, in meters per second, by plugging an
optional hot wire anemometer sensor into a side jack on the unit.

Determine thermal comfort indices, Predicted Mean Vote (PMV) and Predicted Percent
Dissatisfied (PPD), using Detection Management Software (DMS).

Waterless Wetbulb

The Waterless Wetbulb is an estimated measurement using the % of Relative Humidity, Dry Bulb
Temperature, and Globe Bulb Temperature to determine the psychrometric wetbulb. The
psychrometric wetbulb value is adjusted based on air flow to provide the waterless wetbulb
estimate.

Computing Waterless Wetbulb and Wind Speed

When computing the waterless wetbulb, you can increase accuracy by setting the air flow to the
current environments wind speed. The recommended air flow setting for an indoor environment
is 0.3 m/s unless otherwise determined with an air-probe measurement (available only on the

QTº46 model). The recommended setting for outdoor environment is 2.0 m/s.

NOTE: To convert wind speed from miles/hour to meters/sec use the following formula:

 Miles/hour * .447 = meters/sec. (Example: If the average wind speed is 5 mph,

then enter 5*.447 = 2.2 meters/sec.)

If you are using the QUESTemp°46 with the Air Probe attached, you would not set the air flow
setting. (It will automatically calculate with the current reading.)

See “Setup for Waterless Wetbulb measurement” for details on setting the Air flow.

Measurements

WetBulb Globe Temperature

WetBulb Globe Temperature

The WBGT is a weighted average of the three temperature sensors using the following formulas:

 WBGT (indoor) = 0.7WB + 0.3G (denoted as “WBGTi” on the display)
 WBGT (outdoor) = 0.7WB + 0.2G + 0.1DB (denoted as “WBGTo” on the display)

The resulting WBGT values can then be compared to indices of work-rest regimens (stay times)
based upon workloads.

Stay Times/Rest Times (QTº46 only)

Stay times represent how long a worker should be able to safely work under heat stress
conditions. Select one of four indices for displaying and printing from the unit: ACGIH Stay
Times, NAVY PHEL’s, U.S. Navy/Marine Corp. Ashore Flag Conditions, or EPRI Action Limits.
Refer to Appendix B for more information on the indices.

Heat Index/Humidex

The Heat Index is determined using the dry bulb temperature and relative humidity. Based upon
charts available from the U.S. National Weather Service, Heat Index represents how an average
person feels relative to climate conditions. For a given temperature, the higher the humidity, the
higher the heat index.

The Heat Index is defined over a temperature range of 70°F – 120°F (21°C – 49°C) and a
relative humidity range of 30% – 99%. Outside of this range, the instrument will show dashes in
the display for the Heat Index.

The Humidex, used primarily in Canada, works on the same concept as the Heat Index. The
values are slightly different. The Humidex is defined over a temperature range of 70F - 109F
(21C - 43C) and a relative humidity range of 20% - 99%. Outside of this range, the instrument
will show dashes in the display for the Humidex.

Air Flow

The QUESTemp 46 measures air flow if TSI Quest’s Air Probe accessory is used. The Air
Probe uses an omni-directional anemometer sensor that measures air flow between 0 and
20 meters per second in 0.1m/s increments. See “Air flow Functionality” for more details.

Measurements

Thermal Comfort

Thermal Comfort

Thermal comfort readings for indoor environments are a benefit of Detection Management
Software (DMS) and are not displayed or printed from the instrument directly. Readings are
derived from the dry bulb, relative humidity, mean radiant temperature, air flow, and user entered
parameters of clothing, metabolic rate and external work.

Thermal comfort indices, Predicted Mean Vote (PMV) and Predicted Percent Dissatisfied (PPD),
help predict the thermal satisfaction level of a person with their indoor environment. The PMV is
a rating scale of +3 to -3 where +3 is much too warm, -3 is much too cool, and 0 is thermally
neutral. The PPD reflects what percent of people in a given location would be dissatisfied with
their thermal surroundings.

The formulas used by DMS to derive the PMV and PPD come from the international standard
ISO 7730 “Moderate thermal environments - Determination of the PMV and PPD indices and
specification of the conditions for thermal comfort”.

Performing an Electronic Sensor Check

Electronic Sensor Check

A verification module, Quest model 053-923, may be used to check the operation of the
QUESTemp’s wet bulb, dry bulb, and globe. The purpose is to verify that the electronic
components are within a specific range with known values and a known source. The temperature
tolerances should be within ±0.5oC.

 NOTE: If the sensors are outside of the tolerances, this indicates the sensor alignment should

be serviced off-site for calibration.

Performing an Electronic Sensor Check

1. Ensure the instrument is reading in Celsius prior to your electronic sensor check.
 To change the temperature setting, select Setup from the main menu. Then, either

Fahrenheit or Celsius will appear on the screen. When selected, press I/O enter key to
switch between settings. For more information, refer to Operating.

2. Remove the top sensor bar, place to the side, and plug in the verification module into the center

pins of the sensor housing.

3. Verify the measurement readings on the screen are within ±0.5C tolerance to the readings

printed on the verification module label. Example below:

a. Wet Bulb (WB) – 11.1C
b. Dry Bulb (DB) - 45.3C
c. Globe (G) – 69.2C
 NOTE: Relative humidity (RH) is not valid on this instrument.

4. Once completed, remove verification module and place sensor bar back on the instrument.

(Tighten down the two bolts.) Change the Celsius reading back to Fahrenheit. (Refer to step
1 a-b.)

RH Sensor Alignment

Sensor Alignment

For highly accurate measurement readings, you should align your QUESTemp° 44/46 prior to
data logging. For the RH sensor, it is recommended to align with a High concentration level using
the 75% sensor salt, NaCl (sodium chloride), or a Low concentration level using the, the 33%
sensor salt, MgCl (magnesium chloride). (See ColePalmer.com to order sensor alignment salts.)

RH Sensor Alignment

1. To open, navigate to the main menu and select View by pressing I/O Enter key (see A). A

measurement screen will appear (see B).

5. Place a latex finger cot (user supplied) over the humidity sensor in order for the sensor to

stabilize quicker about 15 minutes (or up to 60 minutes without). NOTE: Latex finger cots can
be found at various hardware stores or online such as ColePalmer.com.

Figure 1-22: Sunshield & placement of finger cot prior to RH verification

6. Place the Salt container, with the salt alignment cap removed, over the RH sensor (middle

sensor). Allow level to stabilize for at least 15 minutes. (Refer to Figure 1-23.)

 About sensor alignment: if readings are within ±0.5%, a change in sensor alignment is

not required. Skip to step 7 to return to main menu.

 NOTE: For a High alignment, use the 75% sensor alignment salt (NaCL) and for a Low

alignment, use the 33% alignment salt (MgCl).

Air Flow Functionality

(Available using TSI’s Air Probe on QUESTemp° 46 model only)

Air flow is measured in meters per second over a range of 0 to 20m/s in 0.1m/s increments. The
sensor should be placed or held perpendicular in the air stream. Unlike many anemometers, the
omni-directional sensor does not require rotating to find the maximum reading. Be careful not to
block the air flow with your body during measurements. The sensor’s measuring tip is fragile; be
cautious if measuring in ducts.

The Air Probe may be either hand-held or mounted behind the QUESTemp° 46 using the
mounting bracket hooked to the sensor bar beneath the center bulb sensor. (See Figure 1-22
below.)

A green lamp indicator in the Air Probe indicates that it is turned on and the battery is good. If the
green indicator turns off while the switch is in the On position, replace or recharge the battery.

Check

Operating Sequence

Operating Sequence

1. Turn Flow On in the setup menu of the QUESTemp46.

2. Plug the Air Probe into the port labeled Flow on the side of the QUESTemp 46.

3. Turn on the Air Probe ON and make sure the green lamp is lit.

 In the View or Run modes, air flow is displayed on the fifth screen.

Data Logging Air Flow

To data log air flow in the QUESTemp 46, the following two conditions must be met.

1. First, turn Flow On in the setup menu.

2. Second, make sure that a temperature sensor bar is connected to the Sensor 1 location (top)

of the QUESTemp46. Flow prints out with the Sensor 1 data therefore air flow data will only
be reported if a sensor bar is plugged in. Air flow is recorded during the run mode at the
interval the QUESTemp 46 is setup for.

Batteries for Air Probe

The Air Probe uses a single NiMH Black&Decker® VersaPak™ Gold battery. Typical operating
time of the battery is between 6 and 8 hours.

To change the battery, push in and twist, counterclockwise, the cap on the bottom of the Air
Probe. Pull out the battery. Insert a fully charged battery and replace the cap.

To recharge the batteries, set the battery into the VersaPack charger. The supplied charger
accepts one or two batteries. A full charge takes 9 hours. An indicator light shows that the battery
is properly charging and it will remain on as long as the battery is in the charger. Continuous
charging is not a safety concern.

Operational Check

A verification module, TSI model 053-923, may be used to check the operation of the
QUESTemp. Remove the top sensor bar and plug the verification module into the top of the unit.
With the QUESTemp set to read in degrees Celsius, verify that the displayed readings match
those printed on the module within ±0.5C.

If the readings are not within the ±0.5C tolerance, then have the unit serviced and calibrated.

Operational Check

25

The two-position switch located in the battery compartment must be
set by the user if the power supply method is changed. The up
position is for the 9-volt battery. The down position allows for either
the AC adapter or the rechargeable batteries. The AC adapter will
trickle charge the rechargeable batteries if they are in place or it will
simply allow for line power operation of the unit.

Figure 1-28: 9-volt battery

9-Volt Alkaline Battery Replacement

Power Options

There are three options for powering the QUESTemp° 46: a 9-volt alkaline battery, a NiMH
(Nickel Metal Hydride) rechargeable 6-cell battery pack, and an AC adapter. A door on the back
of the unit allows the user access to the 9-volt battery. The rechargeable battery pack is located
inside of the unit. If the rechargeable battery pack ever needs to be replaced, it can be accessed
by removing the screws from the bottom panel of the unit.

9-Volt Alkaline Battery Replacement

WARNING: Replace batteries only in a non-hazardous environment.

The 9-volt battery should be replaced or the NiMH battery pack should be recharged when the
voltage drops below 6.4 volts. The battery voltage is displayed when the instrument is turned on.
While turned on, the battery voltage can be displayed at any time by pressing the up or down
arrow keys to move through the display until the battery voltage screen appears. If, while
operating, the battery voltage drops below 6.4 volts, the display will automatically switch to the
display showing the battery voltage along with a low battery message. After a low battery occurs,
the unit will continue to operate for approximately 8 hours. When the battery voltage falls to 6.2
volts or below, the unit will automatically turn off.

Replace only with an approved 9-volt alkaline battery.
