Overview

The AM4215R-TM Series is an NDIR triple-refrigerant (R454A, R454C, R455A) leak sensor for HVAC&R refrigerant detection systems, measuring 0-100% LFL at 0.1% LFL resolution from -40 to +95℃, with IP54, anti-frost heating, dual relays and UL 60335-2-40 / 2-89 certification.

Key Features

  • NDIR (Non-dispersive Infrared) technology
  • Triple refrigerant gas detection of R454A, R454C, and R455A.
  • Matrix calibration to ensure accuracy under full working temperature
  • Fast response
  • Automatic heating mechanism for anti-condensation and recovery from frost
  • High temperature resistance supports continuous operation at 95℃
  • IP54 protection level
  • Salt spray corrosion resistance
  • Long lifespan over 15 years
  • UL 60335-2-40 & UL 60335-2-89 certified
