PST gas detectors are designed with patented nondispersive infrared technology for the detection and measurement of the presence of refrigerant gases. To meet the growing need for lower global warming potential (GWP) refrigerant gases, Dynament offers detectors for both flammable (A3, A2, A2L) and non-flammable (A1) refrigerants. Dynament NDIR detectors have a twenty-year history of meeting and exceeding gas detection needs in the most challenging of environmental applications. The Axiom series platform provides a linearized, high-resolution measurement of refrigerant gases over the lower explosive limit range.
