Frequently Asked Questions
What does the AimSafety PM100-NO2 detect?
The PM100-NO2 detects Nitrogen Dioxide (NO2) over a range of 0 to 20 ppm with 0.1 ppm resolution, using a diffusion-type electrochemical cell.
What are the factory alarm set points on the PM100-NO2?
The low alarm is 2.5 ppm and the high alarm is 5 ppm. Both are user selectable through the PM Link PC interface and software.
How long does the PM100-NO2 last?
The PM100 operates continuously for two years, based on two minutes of alarm per day with limited IR communication use. The lithium battery and sensor are not replaceable, and the monitor displays a warning during its final 30 days of life.
Can the PM100-NO2 be turned off?
No. Once activated the PM100 is designed to run continuously for the life of the instrument and cannot be switched off. Check the activate-by date on the box before putting a unit into service.
Is the PM100-NO2 intrinsically safe?
Yes. It is certified to UL-913 and CSA-C22.2 No. 157 for Class I, Division 1 and 2, Groups A, B, C and D, and carries ATEX II 1 G Ex ia IIC T4 Ga IP67, IECEx Ex ia IIC T4 and INMETRO approvals.
Can the PM100-NO2 be used with the PM100-STN calibration station?
No. The PM100-STN bump test and calibration station is published as compatible with the CO, H2S and O2 models only. Bump test and calibrate the PM100-NO2 using the PM Link PC interface with a calibration hood, regulator and the matching calibration gas.
