PGM-IR Portable Area Gas Monitor Model 3015-5696 PGM-IR Portable Area Gas Monitor - For Halogen-Based Refrigerant Gases (Including Rechargeable Battery Pack, 120-240VAC Charging Adapter and Softcase) 3015-8001 PGM-IR Portable Area Gas Monitor - for carbon dioxide 3015-4790 PGM-IR Portable Area Gas Monitor - for nitrous oxide 3015-5148 PGM-IR Portable Area Gas Monitor - for sulfur hexafloride Our Most Powerful, Most Accurate Portable Refrigerant Detector The most powerful, accurate portable refrigerant detector 1 ppm Minimum Detectable Level Detect leaks that other instruments can’t Cut leak inspection times Fast response time finds leaks quickly Infrared sensor unaffected by changes in temperature and humidity Real time ppm display quantifies leak to help easily find the source 50+ refrigerants accurately detected Halogen CO2, N2 and SF6 versions available Description The PGM-IR offers superior performance and functionality for low ppm level leak detection of refrigerants, Carbon Dioxide, Nitrous Oxide or Sulfur Hexafluoride. A built-in library of 50 refrigerants enables the PGM-IR to accurately detect the smallest leaks at their source. The unit is immune to sudden changes in temperature or humidity and to over-exposure. The PGM-IR requires no zeroing of positive readings with extended exposure to gas. It has a data logging capacity of up to 200 readings. With its high flow rate, real-time ppm concentrations or TWA values are displayed instantly with corresponding audible tick-rate indicator to precisely pinpoint leaks. Rapid clearing time enables accurate ambient-air leak detection using the probe along a chiller or display-case. A re-zeroing algorithm and filter/bladder system allows the unit to be used in contaminated areas without affecting target gas readings. The rechargeable Li-ion battery provides a minimum of 8 hours of runtime for all-day usage.

(3.2 kg) Approvals CE mark; NOT approved for use in classified, hazardous areas Is there a way to determine how many parts per million (ppm) a leak of 0.1 ounce per year (oz/yr) is? A leak of 134a refrigerant measuring 0.1 oz/yr is equivalent to approximately 380 to 400ppm. A leak measuring 0.2oz/yr is equivalent to approximately 760 to 800ppm. 1 Ounce = 28.3495 Gram 0.1 oz/year = 2.83495 g/year (380 to 400ppm) 0.2 oz/year = 5.6699 g/year (760 to 800ppm) Case Study Given 10ppm: 0.00025 oz/yr (Based On 400ppm) = 1ppm = 0.007087380781 g/yr 10ppm = 0.0025 oz/yr = 0.0708738078 g/yr Note: The PGM-IR is really a leak detector and not an instrument for quantifying the size of the leak. To accurately convert from ppm to g/yr cannot be done because we need to take into account many factors including pressure, temperature, molecular weight, velocity etc.
