POWER REQUIREMENTS

The Sauermann SI-AQ PRO Indoor Air Quality Monitor is a battery-operated Portable device designed to be operated by a qualified engineer/technician to make measurements in buildings and residential facilities. For long-term testing please carefully follow the product safety instructions in Chapter 1.
Power is supplied by a Li-Ion rechargeable battery pack. The battery pack will supply power to the monitor for about at least 8 hours of continuous operation.
A 110 – 240 Volt AC charger having a 12 Volt DC / 2.5A output is supplied with the instrument. The battery charger will fully charge the battery pack in three hours.
You can check the condition of the batteries at any time:
1. By pressing the MEASURE key, (small font screen) and observing the battery icon, located at the bottom of the display.
2. By pressing the MEASURE key, (large font screen), the user can scroll all the way to the
end using the DOWN arrow key to observe the battery life shown in Voltage. When the unit is operating on its internal batteries, the voltage displayed will vary from an initial 8.0 to
8.4 volts (fully charged) dropping slowly to approximately 7 volts (batteries nearly empty). When the battery voltage drops to 7.1 volts a “low battery” warning will appear on the display. Within a few minutes later the instrument will automatically turn off, to preserve the remaining battery power for the sensor bias voltages.

CHAPTER 5
SENSOR LIST
:

SENSORS -TECHNICAL

The great versatility of the SI-AQ PRO Air Quality monitor is partly due to the large number of sensors available within a single monitor.
These sensors are primarily gas sensors and can be grouped into four categories based on their principle of operation:
1. Up to two (2) electrochemical gas sensors
2. One (1) NDIR (infrared gas sensors) – CO2
3. Non-gas sensors (Temperature, Humidity, Pressure, Velocity, and Barometric pressure) sensors
The main section of the monitor houses all the electrochemical and NDIR gas sensors, battery pack, and PC board. On the bottom of the unit, there is a black external sampling system for Ambient Temperature, Relative Humidity, and Barometric Pressure.
The figure below shows the internal manifold of the gas sensors inside the unit:

1. ELECTROCHEMICAL SENSORS
All electrochemical sensors are mounted on fitted socket fittings for easy installation and removal.
The electrochemical sensors are described below:
A. Nitrogen Dioxide sensor (NO2)
This is a three-electrode sensor that responds to nitrogen dioxide gas. Nitrogen dioxide is a “sticky” gas and this sensor’s response is usually the slowest of all sensors.
B. Sulfur Dioxide sensor (SO2)
It is a three-electrode sensor that responds to sulfur dioxide gas. It is equipped with an inboard filter to remove interference from H2S gas and other acidic gases.
C. Nitric Oxide sensor (NO sensor)
This is also a three-electrode sensor that responds to nitric oxide. It is equipped with an inboard filter to remove any interference from other acidic gases.
The nitric oxide sensor requires a constant bias-voltage for proper operation. This is supplied by the monitor’s battery. If the battery voltage drops below a certain value the monitor will turn off automatically to maintain the sensor bias. If, however, the battery voltage further drops to near zero, one must wait 24 hours after connecting the battery charger, for the sensor bias to recover.
D. Oxygen sensor (O2 sensor)
This sensor measures the oxygen concentration in the sample. It is a two-electrode electrochemical cell. It has a silver cathode and a lead anode. Oxygen diffuses through a tiny hole and reacts with the lead anode. The reaction produces an electric current. The unit software linearizes the current vs. oxygen response. The cell becomes exhausted when all the lead is consumed.
E. Hydrogen Sulfide sensor. (H2S)
This is a 4-series three-electrode micro sensor with low methanol interference. It measures the concentration of hydrogen sulfide, which is a highly toxic gas. Special precautions must be taken during calibration.
Page 14 of 40
F. Carbon Monoxide sensor (CO)
This is also a three-electrode sensor that responds to carbon monoxide. It is equipped with an inboard filter to remove any interference from other acidic gases.
The optional High Range CO sensor has four electrodes. One measures the concentration of carbon monoxide gas and the other the concentration of any interfering hydrogen gas (It is hydrogen compensated).
G. Formaldehyde (CH2O)
This is also a three-electrode sensor that responds to formaldehyde. It is equipped with an inboard filter to remove any interference from other acidic gases.
This sensor may have interference from H2S, H2, CO, and other reducing gases such as alcohols
In applications where the user is measuring both H2S and Formaldehyde, the Formaldehyde readings could be inaccurate as the levels of H2S increase. Relative measurements could be appropriate in these situations.
2. NDIR (INFRARED) SENSOR (CO2)
A non-dispersive infrared (or NDIR) sensor is a simple spectroscopic device most commonly used to measure CO2 in indoor air quality applications. The main components are an infrared source (lamp), a sample chamber or light tube, a wavelength sample chamber, and the CO2 gas concentration is measured electro-optically by its absorption of a specific wavelength in the infrared (IR).
The SI-AQ PRO Air Quality Monitor is equipped with one standard NDIR infrared sensor capable of CO2 measurement (standard range: 0 - 5000 ppm). This infrared sensor can be substituted for higher CO2 ranges upon special request.
The NDIR options have the following specifications:
GAS RANGE ACCURACY
CARBON DIOXIDE (CO2) 0 – 5000 ppm 2% of reading ±10 ppm
Page 15 of 40
3. NON-GAS SENSORS
a. Ambient Temperature sensor
This is a solid state sensor located on the front panel of the monitor. The ambient temperature is displayed on the MEASURE screen in either °F or °C. The dew point is calculated from the ambient temperature and relative humidity. The dew point is displayed on the Small and Large Font MEASURE screens as DPt.
b. Humidity sensor
This is a solid state sensor located on the front panel of the monitor. The relative humidity is displayed on the MEASURE screen in %RH (% Relative Humidity). The Wet Bulb is calculated from the ambient temperature, relative humidity, and barometric pressure. The wet bulb is displayed on the Large Font MEASURE screen only as WBT.
c. Barometric Pressure sensor
This is a solid state sensor located at the front panel of the monitor. The barometric pressure is displayed on the Small and Large Font MEASURE screens as BP.
d. External temperature sensor (T1)
The thermocouple is located at the bottom right side of the monitor. It can be used with any optional or separate Type K thermocouple probe and/or wire. The T1 temperature measurements are displayed on the Large Font MEASURE screen only as T1.
e. Differential Pressure / Air Velocity sensor.
If the monitor comes with the Differential Pressure option and/or the air velocity option (optional separate L-type Pitot tube and pressure tubing), the internal pressure sensor is a very low range pressure sensor. The Velocity measurements are displayed on the MEASURE screen only as VEL. Differential Pressure is displayed on the MEASURE screen only as ∆P.
Connecting Differential Pressure Hoses:
Connect Metal Hose Connections to either P+ or P- Connection as shown. P+ only will give you Positive pressure; P- only will give you Negative pressure. Plug in both as shown below for Differential Pressure. All single & differential readings are shown on main MEASURE screen as ∆P.

ZERO & SPAN CALIBRATION

Every instrument must occasionally be tested against some known value or standard in order to make sure that its accuracy has not deteriorated. If the instrument is reading outside of the stated accuracies in this manual, the unit should be calibrated by following the procedures described in this chapter.
This chapter will contain all of the information on calibrating and adjusting the SI-AQ PRO IAQ Monitor. The term Span Calibration means comparing the SI-AQ PRO’s readings to a standard concentration (i.e.: calibrated gas bottles) and adjusting/changing the SI-AQ PRO’s individual sensor’s readings to match the standard concentration for the most accurate measurements. The term ZERO calibration refers to the user’s ability to calibrate each sensor with zero concentration of the targeted gas. See Chapter 11, Maintenance, for recommended frequencies of each procedure.
If the unit is returned to Sauermann for Span Calibration, the unit will be shipped back after Calibration with a new Calibration Certificate valid for one (1) year. If the unit is Span Calibrated in the field, the original calibration certificate is no longer valid.

If you have a gas cylinder/bottle of ZERO AIR you can use this for Zeroing ALL of the gas sensors in the SI-AQ PRO. If you do not have this cylinder, please contact Sauermann to purchase our optional Calibration Kit consisting of ZERO AIR & regulator for proper calibration of the SI-AQ PRO (part #: Si­AQ Calibration Kit).
Page 24 of 40
ZERO GAS SENSORS: This will set the zero point of CO, NO, CH2O, NO2, SO2, H2S, and O2 values. Connect Cylinder to the “A” inlet connection on the bottom of the SI-AQ PRO using the optional accessories included in the CALIBATION KIT (Part #: Si-AQ Calibration Kit). See CALIBRATION APPARATUS section below for how to connect.
Have the cursor (reverse color) point to the line:
Zero Gas Sensors
Press the OK key to execute a zero cycle of all the gas sensors. This procedure should last 60 seconds.
At the end of the zero period, the SI-AQ PRO reads the output of all gas sensors (with the exception of the CO2 sensor) and sets them all to zero, and the Oxygen (O2) that it sets to 20.9%.
If no error messages appear at the end of the countdown, proceed with your measurements.
ZERO CO2: This will set the zero point of CO2. You must use cylinder of ZERO AIR for CO2 ZERO CALIBRATION. Connect Cylinder to the “A” inlet connection on the bottom of the SI-AQ PRO using
the optional accessories included in the CALIBATION KIT (Part #: Si-AQ Calibration Kit). See CALIBRATION APPARATUS section below for how to connect.
Scroll down using down arrow key and have the cursor (reverse color) point to the line
Zero CO2 Sensors
Press the OK key to execute a zero cycle of the CO2 Sensor. The monitor will count down from the Zero Time setting as explained above. The recommended Zero Time for the CO2 sensor is 60 seconds.
If no error messages appear at the end of the countdown, proceed with your measurements.
2. ZEROing Sensors using OUTDOOR FRESH AIR (with the exception of CO2)
If you are
not
using bottled ZERO AIR, it is important to select a location where the ambient environment of the monitor is clean from traces of carbon monoxide or other toxic gases. The user should be at least 20-30 feet (6-10 meters) away from any buildings, parking lots, highways, and any other possible exhaust sources. If in doubt of the ambient air, please use the ZERO AIR cylinder.
When you turn the instrument on in clean ambient air, wait at least one (1) minute to allow the monitor to warm up before carrying out the zero calibration.
ZERO GAS SENSORS: This will set the zero point of CO, NO, CH2O, NO2, SO2, O2, and H2S values based on the clean ambient conditions.

Sauermann recommends performing a span calibration of the instrument once every 6 months for maximum accuracy, or at a minimum of once per year. The parameters that require a span calibration are: carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, sulfur dioxide, hydrogen sulfide, oxygen, and formaldehyde. You can carry out all span calibrations in sequence.
Span calibration using your own gas
If you wish to use your own span gas to perform span calibrations you must take certain precautions and follow the instructions below carefully in order to calibrate the sensors properly.
Page 26 of 40
Notice that you will need a number of certified gas cylinders. Make sure that you use a bypass flow meter as shown below in the CALIBRATION APPARATUS section, in order to supply an adequate flow of span gas without developing excessive or insufficient pressure on the sensors.
Make sure the concentration of the calibration gas is within the range of each sensor. Do not use gas that will over-range the sensor.
The CO span gas can be in the range of 30 - 200 PPM, 2% accuracy with balanced nitrogen, preferably.
The NO span gas can be in the range of 10 - 200 PPM, 2% accuracy with balanced nitrogen, required.
The NO2 span gas can be in the range of 10 - 20 PPM, 2% accuracy with balanced nitrogen or air.
The SO2 span gas can be in the range of 10 - 20 PPM, 2% accuracy, with balanced nitrogen, preferably.
The CH2O (Formaldehyde) span gas can be in the range of 0 - 2 PPM, with balance nitrogen, preferably.
The H2S span gas can be in the range of 10 - 20 PPM, 2% accuracy, with balance nitrogen, preferably.
The CO2 span gas can be in the range of 2500 PPM, 2% accuracy, with balance air
Make sure the concentration of the calibration gas is within the range of each sensor. Do not use gas that could over-range the sensor.
For greatest accuracy, it is recommended that you use a span gas value close to the gas concentration you expect to measure.
C. CALIBRATION APPARATUS
During calibration an adequate flow of span gas must be supplied without developing excessive pressure on the sensors. A compressed cylinder of span gas must be equipped with a primary pressure regulator. Connect the regulator of the bottled gas to the SI-AQ PRO “A” inlet in the center port on the bottom of the unit. A simple way to feed the span gas to your monitor is by an open T-connection that will ensure that gas is fed at ambient pressure. The regulator valve is used to control the flow of gas to the monitor. To ensure that the span gas is fed properly and as efficiently as possible, connect a bypass flow-meter at the outlet. Adjust the regulator to maintain approximately 750 cc/min of flow at the outlet.
You must not feed gas to the SI-AQ PRO under pressure and you must not starve the SI-AQ PRO's pump for gas. When feeding the gas, you must maintain a reasonably constant pressure, near ambient pressure.
