Product features

  • Liquid temperature range: Operate across a temperature range of -40°C to 50°C (-40°F to 122°F).
  • Pressure tolerance: Rated for pressures up to 100 bar (1450 psi).
  • Power supply: The switch operates on a 24V AC/DC power supply.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • LED indicators: Provides clear visual feedback when refrigerant is detected.
