LDM150 and LDM150R are simple, reliable and safe solutions for standalone constant monitoring of ANY refrigerant gas. These monitors are a true "plug and play" option! See how these monitors fit any application.

LDM150 uses an integrated sensor for a compact, all-in-one solution.  LDM150R uses a remote sensor for applications where the sensor should be installed separately from the monitor.  See more details in the specifications tab.

  • Low maintenance, single point calibrations
  • Easy field service
  • Three adjustable alarm setpoints
  • Low or high voltage operation
  • Three relay outputs tie to any system or device
  • Designed for any size application
  • Factory calibrated
  • Detects all CFCs, HFCs, HFOs, HCFCs and CFCs
