Overview

The AM4207 Series is an NDIR R1234yf refrigerant sensor for cold-chain transport, highly selective and resistant to high CO2 from fruit and vegetables. Automatic anti-condensation heating, a reference channel with self-compensation and a compact form provide stable, low-false-alarm detection compliant with IEC and UL 60335-2-40.

Key Features

  • NDIR (non-dispersive infrared) technology
  • High selectivity, immune to poisoning gases and CO2
  • High accuracy
  • Automatic heating mechanism for anti-condensation
  • Long-term reliability, no false alarm
  • Fast response
  • Long lifespan
  • Compact design, easy for integration
  • UL 60335-2-40 4th edition and IEC 60335-2-40 7th edition standard compliance
