Frequently Asked Questions
What does the AimSafety PM100-O2 detect?
The PM100-O2 detects Oxygen (O2) over a range of 0 to 30 % Vol with 0.1 % Vol resolution, using a diffusion-type electrochemical cell.
What are the factory alarm set points on the PM100-O2?
The low alarm is 19.5 % Vol and the high alarm is 23.5 % Vol. Both are user selectable through the PM Link PC interface and software.
How long does the PM100-O2 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-O2 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-O2 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.
How is the PM100-O2 bump tested and calibrated?
The PM100-STN bump test and calibration station handles up to four monitors at a time and is compatible with the CO, H2S and O2 models. The PM Link PC interface performs zero and span calibration and retrieves event logs.
