The PGM-IR is an advanced portable monitor that uses long-life non-dispersive infrared (NDIR) sensor technology for analyzing and checking low-level gas leaks.
With very fast response and clearing times, the unit can identify and pinpoint very small levels of refrigerants, nitrous oxide or carbon dioxide gas in ambient air, showing real-time concentrations in either parts per million (ppm) or elapsed time weighted average (TWA) with a resolution down to 1 ppm. For N2O and CO2 are special models available.
The unit self-calibrates in 4 minute intervals by drawing ambient air through its filter to provide a good “zero” baseline, enabling the monitor to be used in contaminated environments without affecting the readings of the target gas. Additional features include datalogging of up to 200 readings, and a leak check mode with "tick-rate" audible / visual alarms. The PGM-IR’s probe helps to locate leaks in small or hard to reach places and provides up to 12 hours operation on a fully charged battery.
