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.

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.
