SST Sensing Axiom Series Refrigerant Infrared Gas Detectors

SST Sensing Axiom Series Refrigerant Infrared Gas Detectors are developed with patented non-dispersive infrared technology to detect and measure the presence of refrigerant gases. The Axiom Detectors provide both flammable (A3, A2, A2L) and non-flammable (A1) refrigerants to meet the growing need for lower global warming potential (GWP) refrigerant gases.

The SST Sensing Axiom Series NDIR detectors achieve and exceed gas detection requirements in the most demanding environmental applications. The Axiom series platform supplies a linearized, high-resolution measurement of refrigerant gases over the lower explosive limit range.

Features

  • Refrigerant gas detectors for R32, R454B, R454C, R290 (Propane), R1270 (Propylene), and R744 (Carbon Dioxide)

The Axiom Diagnostic Tool (ADT) requires a USB-C to USB PC cable connection. Axiom diagnostic information is available through a PC application, which provides real-time gas readings, access to configuration settings (baud rate, Modbus address), and detailed fault information to assist with service and maintenance.
