Product information

To avoid the damage and dangers caused by refrigerant leaks, it is extremely important to follow the recommendations below to ensure that the leak monitoring system is functioning accurately.

  1. Replace visibly damaged monitors and detectors immediately.
  2. Check and test the detectors once every 12 months with diagnostic tool DT300
  • Required by Safety Standard for Refrigeration Systems, EN378:2016.
  1. Replace sensor every 5 years
  • Under normal circumstances, the lifetime of the sensor in the detector is up to 5 years. As a preventive measure, we recommend that ship owners plan for sensor replacements when it is reaching 5 years in operation.

This detector somes with the new sensor, SEN027 (SELF SENSE) with built-in filter that makes the sensor much more resistant against false alarms caused by dust, dirt, liquids, and aerosols.

The change of SEN027 can be performed without any change in alarm settings, and calibration is recommended with DT300 and SM300-SELF SENSE sensor module.


  • Requires connection to a monitoring unit e.g.MPU2C, MPU4C, MPU6C, SPU/SPLS
  • Power supply from monitoring unit
  • Robust non corrosive PC enclosure for installation also in aggressive environments
