2. System Description
WARNING
When using the analyzer for applications with mixed gases other than air, you must first
obtain proper instruction from a certified diving instructor with a nationally recognized
training agency qualified in mixed gas diving. Improper use of this analyzer may result
in incorrect gas analysis which can lead to serious personal injury or death.
WARNING
Although the analyzer is a rugged instrument, careless handling or abuse may result in
damage to the analyzer resulting in inaccurate gas analysis. Inaccurate gas analysis
can lead to serious personal injury or death.
WARNING
Breathing gas must always be analyzed by two separate analyzers, with one used for
gas production and one used for analysis after production. Never depend on a single
analyzer during both gas production and delivery. If analyzer readings do not agree,
both units must be recalibrated. Inaccurate gas analysis can lead to serious personal
injury or death.
The Nuvair Pro VOC Alarm is designed to detect the presence of a volatile organic compound (VOC).
It can be connected to a gas compressor for continuous output reading, or it can monitor ambient air
(using diffusion mode) and will alert personnel in case of dangerous VOC concentrations in the air.
The Nuvair Pro VOC Alarm is a digital measurement instrument with two visible and audible alarms if
VOC value is above or below set values. It is based on a state-of-the-art Photo Ionization Detector (PID)
sensor with long-term stability and easy maintenance. It is possible to replace the internal lamp and
calibrate the sensor without factory assistance. It is strongly suggested to check the analyzer’s alarm
function prior any use (bump test1).
With a resolution of 0.01 ppm (parts per million), the Nuvair Pro VOC Alarm analyzer is designed to
measure volatile organic compounds levels directly from pressurized sources or ambient air.
The analyzer comes in either a handheld or panel mount configuration. It is powered by wall plug-in,
rechargeable lithium-ion battery, or DIN rail. It includes an internally mounted sensor with audible
alarm. The water-resistant case includes a digital display and controls that are environmentally
sealed.
The analyzer also has a 4-20 mA analog output for external devices. The analog output can activate
an optional relay to automatically shutdown/start-up equipment or sound an external alarm when the
analyzer alarm activates.
The analyzer uses a flow adapter cap and flexible tubing to deliver sample gas to the sensor.
Pressurized gases must be regulated to avoid damage to the analyzer.
1“Bump tests” ensure analyzers go into alarm when sensors are exposed to gases that exceed the analyzer’s
setpoint. A bump test is not a calibration test, but rather a test to determine if the analyzer will alarm as
expected.

3. Calibration
WARNING
Improper calibration may result in the use of contaminated breathing gas mixtures,
which may cause serious injury or death to the person.
WARNING
Calibration or use of the analyzer with a low battery may result in inaccurate readings.
Inaccurate gas analysis can lead to serious personal injury or death.
NOTICE
If the analyzer has been subjected to a recent severe change in ambient temperature,
allow it to stabilize for 10 minutes before calibration.
WARNING
When analyzer calibration is performed at different atmospheric conditions than the
gas being measured, a calibration correction value may be required. Improper
calibration may result in the use of incorrect breathing gas mixtures, which may cause
serious injury or death to the person using the gas mixture. All the values are calculated
assuming gas temperature of 21.11°C (70°F) at 1013 mbar (ambient pressure).
Calibration and/or bump tests should be performed at the same temperature and humidity conditions
as the gas being measured. This is not always possible, for example, in a tropical environment where
dry breathing gas from a high-pressure scuba cylinder will be measured after analyzer calibration has
been performed in the warm, humid ambient air. Under these conditions a calibration correction value
may be required, as detailed in the Appendix, or dry air must be used for calibration.
WARNING
Obtain proper training before attempting special calibration procedures. Improper
calibration may result in the use of incorrect breathing gas mixtures, which may cause
serious injury or death to the person using the gas mixture.
For calibrating the sensor at the Isobutylene span value, connect the sensor to the calibration gas for
2–3 minutes and wait until the reading is stable. Once the reading is stable, press <ON/OFF> and
<CALIB> keys simultaneously for a few seconds. Known gas calibration is now complete.
For calibrating the zero, flow pure synthetic air (certified sample gas with 0 PPB VOC content) on the
sensor for at least 5 minutes or when the value reading is stable. Once the reading is stable, press
<ON/OFF> and <PROG> keys simultaneously for a few seconds. Zero calibration is now complete.

power supply of 7–16 VDC. The analyzer can be connected to a gas source or can analyze
ambient air.
4.2. The main page shows PPM (part per million) of Volatile Organic Compound (VOC) related
to Isobutylene in the range 0.01 to 19.99 ppm. Pressing CALIB key it is displayed:
· The Volt output of the battery (BAt) or the external power supply
· The Ambient Temperature in °C (TEM)
· The Sensor mV output (SnS)
· The Milligram per Cube meter (MGM) of the VOC detected related to Isobutylene.
4.3. PROGRAMMING PAGES. Pressing the <PROG> key you will go to the programming
pages (Pr): Correction Factor (CF), Molecular weight (MoL) Alarm1 (AL1), Alarm2 (AL2),
Full scale (FSC), Span Gas Calibration Value (CAL). Press ON/OFF for changing the
pages.
· Correction Factor (CF) is the value of the target VOC to be detected related to Isobutylene.

· Full scale value (FSC) sets the span output value of the instrument for the 4-20 mA output,
if available. The value is related to PPM value that will be displayed at 20mA.
· Span Gas Calibration Value (CAL) is the value of the span calibration gas generally
related to PPM of Isobutylene.
4.4. For changing the digit value into any programming page, press <PROG> key.
4.5. For going to the next digit value, press <CALIB> key.
4.6. For saving the value and going to the next program page, press <ON/OFF> key.
4.7. At the end of the programming pages the unit displays <End>.
DANGER
Never expose gas sensors to pressure or you may cause damage and/or false readings.
Damaged sensors will not provide accurate gas analysis. Most gas analyzers can be
used to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a
regulator. The flow rate of gas must equal 1–5 L/min. To produce this flow, a Flow Restrictor and
Regulator may be required. A faulty Flow Restrictor can lead to a false analyzer reading. Flow
Restrictors should be regularly tested with a Flow Meter. Inaccurate gas analysis can lead to
serious personal injury or death.

Nuvair Pro VOC Correction actors
The Nuvair Pro VOC Alarm analyzer sensor is calibrated using isobutylene, but the PID (Photo Ionization Detector) is
a broadband VOC detector, with a sensitivity that differs for each VOC. If you know what VOC you are measuring,
then the table below will allow you to calculate the concentration for your specific VOC. Remember, these are
approximate values, so for best accuracy you should calibrate with the relevant VOC.
The table includes six columns:
1
2
3
4
5
6
Gas/VOC The most common name for the VOC. If you can not find the name of your VOC of concern, please
email the Nuvair sales team at [e-mail] for assistance.
CAS No. You can find the VOC using the CAS No.: Ask your supplier.
Formula To assist in identifying the VOC.
Relative Response/ Correction Factor (CF) Also called the Response actor (R ). Multiply the displayed
concentration by the Relative Response/ C / R to calculate the actual concentration of the VOC.
Relative sensitivity (%) This is the inverse of the correction factor, specifying the percent response of the VOC,
relative to isobutylene. If less than 100%, then the VOC is less responsive than isobutylene; if the relative
sensitivity is greater than 100%, then the VOC is more responsive than isobutylene. Relative sensitivity (%) is
specified the same way as cross-sensitivity for toxic gas sensors.
Minimum Detection Level (MDL) Also called Minimum Detectable Quantity (MDQ). Typical lowest
concentration that can be detected. The PID-AH2 has greater sensitivity than the PID-A12, so the MDL for the
PID-AH2 will be much less than the MDL for the PID-A12.
The Relative Response/ C / R is measured in dry air; high humidity will reduce this factor by 30% to 50%, so the C /
R should be increased in high humidities.
VOC Response
The PID can not measure all VOCs or gases: two types of VOCs are not measured:
NR:
NV:
No response. The lamp does not ionize the VOC and the VOC cannot be measured.
The vapor pressure of the VOC at 20°C is less than a few ppm, so this Semi-Volatile Organic Compound
(SVOC) cannot be measured.
NA: Not available
Occasionally you will be measuring a mixture of VOCs. If the total concentration is within the linear range of your PID,
then it is reasonable to assume that the concentrations are additive without interference between the different VOCs.
Remember that if you are measuring a combination of VOCs, then accurate measurement of one of these VOCs will be
difficult; without careful data analysis, you will get only a C averaged measurement*. Be cautious when reporting actual
VOC concentration if you know that there may be several VOCs present.
Balance Gas
The relative response is measured in laboratory air, with 20.9% oxygen, balance nitrogen. Some gases absorb UV light
without causing any PID response (e.g. methane, ethane). In ambient atmospheres where these gases are present, the
measured concentration of target gas will be less than is actually present. Methane absorbs UV strongly, so for accurate
measurements in methane containing atmospheres, calibrate with a calibration gas containing the expected methane
concentration. 50% LEL methane reduces the reading by up to 50%. Gases such as nitrogen and helium do not absorb
UV and do not affect the relative response.
The correction factor for a gas mix containing PID detectable gases A, B, C with response factors R (A), R (B), R (C),
in relative proportions a: b: c is given by:
C (mix) = 1 / [(a/C (A) + b/C (B) + c/C (C)]
