COMPLETE LIST OF AVAILABLE REFRIGERANT SENSORS
NET offers the most complete range of Non-Dispersive (NDIR) sensors on the market today for refrigerant gas detection: 44 common gases, plus two more currently under development.
Those gases are available across 3 different platforms (IRNET PRO, IREF PRO, IREF LITE) and the available ranges vary according to the specific gas. For example, non-flammable refrigerants may be available only in ppm range, while some gases may be available only on the IREF PRO platform, which is our longest standing refrigerant sensor. Other gases may be detected using a sensor calibrated for a different refrigerant plus a cross factor. Please note that several cross factors are available for gases for which a dedicated sensor is also available.
IRNET PRO, IREF PRO and IREF LITE all share the same dimensions, footprint and interface. In other words, they are perfectly interchangeable and you switch from one to the other without any modification to your interface electronics.
To provide more clarity, we have compiled the summary table below, where you will find the complete listing of refrigerant sensors available at NET (listed by ASHRAE number), complete with their type/prefix and refrigerant safety classification according to ISO 817:2014.
Alongside each gas we indicated which range and on which platform this is available:
- ppm PRO – gas available in ppm (typically, 0-2000ppm) on the IREF PRO range
- ppm PRO CF* – gas available in ppm applying a cross factor to an IREF PRO sensor calibrated for another gas (learn more here)
- ppm LITE – gas available in ppm (typically, 0-5000ppm – 0-10.000ppm for R-32 and R-410a)) on the IREF LITE range.
- ppm LITE CF* – gas available in ppm applying a cross factor to an IREF LITE sensor calibrated for another gas.
- %LFL LITE – gas available in 0-100%LFL on the IREF LITE range.
- %LFL IRNET – gas available in 0-100%LFL on the IRNET PRO range.
- %LFL IRNET CF* – gas available in %LFLapplying a cross factor to an IRNET PRO sensor calibrated for another gas (learn more here).
To learn more about the differences between IREF PRO and IREF LITE, read our dedicated article.
For example:
R-134a, an Hydrofluorocarbon (HFC) with safety classification A1 (non-toxic, non-flammable), is available in ppm range both on the IREF PRO (0-2000ppm) and IREF LITE (0-5000ppm).
Or:
R-454a, an Hydrofluoroolefin (HFO) with safety classification A2L (non-toxic, flammable with lower burning velocity), is available in ppm range applying a cross factor to an IREF PRO sensor calibrated for another gas and in 0-100%LFL range (0-6.3%vol) both on the IREF PRO and IREF LITE.
