The Honeywell REX-C700 is a fixed refrigerant gas leak detector designed for early warning of harmful refrigerant leaks in HVAC/R systems. Using a semiconductor sensor, it detects CFCs, HFCs, and HCFCs with adjustable alarm thresholds (0-1,000 ppm). The device features two SPDT relays (5A @ 250V AC) for triggering ventilation systems or alarms. With IP65-rated housing, it is suitable for harsh environments, including cold rooms and industrial facilities.
