E2639-HFC is a halocarbon refrigerants detector designed for reliable gas leak monitoring in industrial and commercial environments. It detects a wide range of refrigerants such as R-22, R-134a, R-404a, R-410a, and new-generation low-GWP gases like R-1234yf. Equipped with dual analog outputs, RS485 Modbus RTU, relays, and optional WiFi configuration, the device ensures flexible integration into safety and automation systems. Its robust IP65 enclosure, long sensor lifetime, and advanced diagnosti
