RM7000 VRF Dual Beam Infrared Refrigerant Leak Detector For Indoor Spaces


Key Features:

  • Specifically designed for use in detecting VRF system refrigerant leaks of R410a, R407a/c and other refrigerants in occupied spaces.
  • Long life sensor technology (10+ years), featuring a dual-channel, patented, NDIR infrared sensor that is dual-channel, patented, NDIR infrared sensor that
  • Built in, continuously operating sensor diagnostics that can immediately identify transmitter malfunctions and sensor end-of-life (not possible with most gas sensors).
  • Ability to do a complete functional test of the device in 5 seconds using a strategically placed magnet.
  • Low profile enclosure designed to mount in a standard two-gang electrical box with minimal projection into the room to prevent occupant damage to sensor. White faceplate is easily painted to match room decor. Available without AirTest label.
  • Modbus RTU, RS485 communication indicates local gas concentration. Two alarm relays (SPDT) activates at 1000 ppm (with 76dB buzzer) and 1800 ppm audible buzzer (76 dB).
  • Incorporates unobtrusive LED status indication: Green – Operating, Amber – >1,000 ppm, Red >1,800 ppm.
  • Version for 24VDC, 24VAC and 120VAC operation.
  • Measurement range of 0-5,000 ppm, with accuracy of ± 250 ppm for levels below 2,500 ppm.
  • Fast response. Detects 90% of current reading in less than 30 seconds. Minimal time necessary for bump tests or calibration checks if required.
  • Lowest lifetime total cost over 10+ year sensor operating life.
  • No maintenance required over sensor life.
  • 5-year product warranty.
  • Configured to specifically measure the refrigerant gas targeted.
