PGM-IR Portable leak detector

  • Reduces leak inspection time by 50%
  • Leak detection already at the level of 1 ppm for all detected gases
  • IR sensor insensitive to temperature and humidity influences
  • Frequency voice buzzer, real time ppm reading
  • Easy location of leaks in refrigerated display cases

PGM-IR offers excellent quality and functionality in the detection of low ppm leakages for refrigerants, carbon dioxide, nitrogen dioxide, sulfur hexafluoride. The built-in library of 50 refrigerants allows PGM-IR to accurately detect the smallest spills at critical points. The module is resistant to sudden changes in temperature and humidity as well as to gas exposure in a concentration exceeding the scale. PGM-IR does not require zeroing in case of prolonged contact with the detected gas. Built-in memory allows you to save up to 200 readings.

Thanks to the high flow rate, the actual concentration in ppm or TWA is fed directly to the display. In parallel, in order to locate the leak more precisely, an acoustic signal is generated that corresponds to the concentration being read.

Fast zeroing time allows accurate detection of leakage using the probe, by sweeping the refrigeration unit or gas outlet locations. The automatic zeroing algorithm and the filter system allow the system to be used in dirty zones, with no visible external influence on the reading value. The lithium-ion battery allows a minimum of 8-hour continuous operation.
