Bacharach PGM-IR Portable Gas Monitor and Leak Detector for N2O Gasses

Find leaks fast! Ultra low resolution detects changes down to 1 ppm

The PGM-IR portable N2O monitor delivers superior performance for low-ppm leak detection of nitrous oxide. The unit is resistant to sudden changes in temperature or humidity and extended gas exposure does not require zeroing of positive readings. It also stores up to 200 readings for later analysis.

With a high flow rate and real-time ppm display, the PGM-IR instantly provides audible tick-rate feedback to precisely pinpoint leaks. Rapid clearing times allow accurate ambient-air measurements along chillers or display cases. A re-zeroing algorithm combined with a filter and purge bladder system ensures reliable readings even in contaminated areas. Powered by a rechargeable Li-ion battery, the monitor delivers a minimum of 8 hours of runtime for all-day use.

Key Features & Benefits

Proprietary infrared (NDIR) sensor accurately detects the presence of a target gas down to an industry-leading 1 ppm Minimum Detection Level (MDL)
Detects and measures N2O in refrigerant applications
N2O detection range of 1 to 1,000 ppm
Automatically logs up to 200 gas readings that can be recalled later for analysis
Eliminates false alarms with use of non-dispersive IR source and sample draw system
Visual and audible gas alarm indicators activate when the detected gas level exceeds a user-defined trip point
Backlit display with real-time concentration readings and audible indicator help users track the smallest leaks to their source
Extensive self diagnostics provide both visual and audible indications when a fault occurs
Battery powered, providing a minimum of 8 hours of operation
