This is the new and improved refrigerant leak detection sensor for general application. Can be used for detecting all the CFC, HCFC, HFC refrigerants and hydrocarbons. NB: Special sensors for Ammonia available on request

Product information


  • Working temperature range -20° C to +50° C (-4° F to +122° F)
  • IP 44 rated
  • Improved sensor housing
  • Improved sensor with filter to minimise false alarms from background gases
  • Improved sensor PCB design with incorporated test points
  • Simplified annual maintenance / testing procedures
  • Field adjustments to the sensor sensitivity can be carried out very easily. Sensitivity can be set as low as 100 ppm
  • Factory supply setting is 500 ppm for low level and 1,000 ppm for high level


  • Crew safety: safeguards crew members from long-term exposure to high levels of leaked refrigerant gas in enclosed spaces
  • Cost saving: helps reduce costs due to accidental loss of refrigerants from unmonitored leaks
  • Environmentally sound solution: reduces the risks of global warming and damaging the ozone layer by instantaneous warning of leaks
  • Class compliant: the leak detection system is compliant with LRS requirements for their EP notation and the DNV Clean notation


Directions for use

Mount approximately 1 meter above floor level (most refrigerants are heavier than air)

In areas with lot of air movement, locate the sensor downstream of the system to be detected

Connect to a spare channel in the Monitor using the cable provided (please read the instruction manual carefully)
