Honeywell Analytics S301-IRF-R123 Gas Sensor R-22 Versatile Application: Validated for useThe Honeywell Analytics S301 IRF R123 is an industrial grade R123 refrigerant gas sensor designed for integration with the 301C controller. Engineering for precision in mechanical rooms and chiller plants, this infrared based transmitter replaces legacy models including the 301 IRFS R123, M 505413, and VA301IRFSR123. Utilizing non dispersive infrared (NDIR) technology, the S301 IRFS provides high selectivity detection of R123, minimizing cross
