Introduction
Up and Running Overview
Introduction
The QUESTempº 34/36 models are portable heat stress monitors that are designed to be rugged,
easy-to use instruments to quickly and accurately assess the potential for individual heat stress
based on environmental conditions.
QUESTempº Models
The QUESTempº 34 and QUESTempº 36 models measure and calculate the dry bulb
temperature, wet bulb temperature, globe temperature, WBGT indoor index, WBGT outdoor
index, relative humidity, and Heat Index or Humidex. These models support RS-232
communications and works with the optional software analysis program, TSI Detection
Management Software (DMS).
With the QUESTempº 36, you have the capability to display stay times in order to manage
work/rest regimens. Guidance is based on the screening criteria for heat stress as defined in the
ACGIH TLV Handbook, U.S. Navy PHEL charts, and EPRI Action Limits. (See Appendix B for
detailed chart information.)
An additional feature with the QUESTempº 36 is an optional detachable air-probe for measuring
air velocity (wind speed) to determine appropriate levels of indoor thermal comfort monitoring.

Placement for Monitoring/Testing
The QUESTempº 34 & 36 model 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.
NOTE: Before measuring, allow 10 minutes for the sensors readings to stabilize.
Sensors

The natural wet bulb thermometer
gives an indication of the effects of
humidity on an individual. Relative
humidity and wind speed are taken
into account by measuring the
amount of evaporative cooling taking
place at a thermometer covered with
a moistened wick.

Check Wick and Fill Natural Wet Bulb
The QUESTemp° Heat Stress Monitor uses a cotton wick immersed into a reservoir containing
distilled water. DO NOT use ordinary tap water, as the contaminants that are left behind after
evaporation will shorten the life of the wick and cause high readings. If the wick is discolored it
should be replaced. To replace the wick, slide the old wick off the top of the sensor. Place a
new wick over the sensor, making sure that the bottom of the wick is down in the reservoir.
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.

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.
Relative Humidity Sensor
A relative humidity sensor is located in a compartment inside of the sensor bar housing. Slots in
the housing allow air to circulate around the sensor.

Tri-sensor Calculation and Remote Cable
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 60C.
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 36 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.

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)
Measurements
Wet Bulb Globe Temperature
Measurements
The QUESTemp 34 & 36 data logging area heat stress monitor directly senses the four
parameters: ambient or dry bulb temperature (DB), natural wet bulb temperature (WB), globe
temperature (G), and relative humidity (RH).
The QT 34/ 36 compute the Wet Bulb Globe Temperature (WBGT), stay times for three
possible indices (QT 36 only), 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 QUESTempº 36 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.
Using Detection Management Software (DMS), you can determine the thermal comfort indices,
Predicted Mean Vote (PMV) and Predicted Percent Dissatisfied (PPD) (with the QUESTempº
36 model only).
Wet Bulb Globe Temperature
The WBGT is a weighted average of the three temperature sensors, a globe thermometer, a
wet bulb thermometer, and a dry-bulb thermometer, using the equations listed below.
The resulting WBGT values can then be compared to indices of work-rest regimens (stay times)
based upon workloads.
Stay Times/Rest Times (QTº36 only)
Stay times represent how long a worker should be able to safely work under heat stress
conditions (available on QUESTempº 36 only). Select one of the three indices for displaying
and printing from the unit: ACGIH Stay Times, NAVY PHEL’s, or EPRI Action Limits. (For
setup, refer to “Setup.” For detailed rest times refer to charts in Appendix B.)
Measurements

Heat Index/Humidex
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 70F – 120F (21C – 49C) 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, functions similar to the Heat Index concept. The values are
slightly different. The Humidex is defined over a temperature range of 70F – 109F (21C – 43C)
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 36 measures air flow if the 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
0.1 m/s increments. See “Air Flow Functionality,” for more details.
Thermal Comfort (QUESTempº 36 model only)
Thermal comfort readings for indoor environments are a benefit of DMS software 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 software 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.”

Air Flow functionality
(Available using TSI’s Air Probe on QUESTempº 36 model.)
Air flow is measured in meters per second over a range of 0 to 20 m/s in 0.1 m/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 36 using the
mounting bracket hooked to the sensor bar beneath the center bulb sensor. (See Figure 1-21
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.
To connect, follow steps 1-3 below.

Operating Sequence
Operating Sequence
1. Turn Flow On in the setup menu of the QUESTemp 36 Heat Stress Monitor.
2. Plug the Air Probe into the port labeled Flow on the side of the QUESTemp 36.
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 36, 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 36. 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 36 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
20
The 2-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 1-22: 9-volt battery
Operational
Check
Power options
Operational Check
A verification module, TSI model 053-923, may be used to check the operation of the
QUESTemp° Heat Stress Monitor. 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 ±0.5C.
If the readings are not within the ±0.5C tolerance, then have the unit serviced and calibrated.
Power options
There are three options for powering the QUESTempº 36: 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.

NiMH Battery Pack
WARNING: Recharge batteries only in a non-hazardous environment.
The NiMH rechargeable battery pack is charged in the instrument using TSI’s AC 120V AC to 9V
DC adapter (part #015-910) or 220V AC to 9V DC adapter (part #015-680). A discharged battery
pack requires an “overnight” charge of 16 hours (for the 120V adapter). Leaving the AC adapter
plugged in for extended lengths of time or when operating the instrument will not harm the
rechargeable batteries.
