Refrigerant gas refrigerant gas sensor AM4205H-LC-I-R32/R454B

R32R454BR290

Product overview
AM4205H-LC-I-R32/R454B is an NDIR refrigerant gas sensor designed for A2L refrigerant dual gas R32/R454B leak monitoring in HVACR industry. 


Based on NDIR technology, the AM4215H-LC-I leverages a robust gas chamber design, a smart compensation algorithm, and matrix calibration to provide high accuracy and long-term stability over the full operating temperature range. Its dynamic heating control mechanism prevents condensation to avoid false alarms at harsh working temperatures up to 95C. Fast response time of T40 ≤ 30 seconds fulfills timely leak detection and rapid safety alarm. 


AM4205H-LC-I-R32/R454B features an IP54 protection rating with an integrated wire harness design to make the sensor with compact dimensions flexible to adapt to different installation scenarios.


AM4215H-LC-I dual gas compatibility enables the end customers flexible inventory management. It is compliant with UL 60335-2-40:2022 Ed.4 Annex LL and certified by Intertek ETL. It is a reliable, high-performance solution for refrigerant leak detection for HVAC&R applications, including residential and commercial air conditioners, heat pump, industrial cooling and so on.
