Crowcon Xgard Bright Fixed Gas Detector

The Crowcon Xgard Bright is an addressable fixed-point Gas Detector with a large OLED display and non-intrusive calibration. It combines 4-20mA, Modbus and optional HART over a 4-wire addressable design, with onboard alarm and fault relays for fast, low-maintenance installation.

Looking for an addressable fixed-point Gas Detector with a clear local readout? The Crowcon Xgard Bright from Hinco Instruments continuously monitors hazardous gas levels and shows live readings on a large OLED display. Non-intrusive calibration and magnetic-key configuration keep the cover closed in hazardous areas, cutting maintenance time and improving safety. Its 4-wire addressable design reduces cabling, while 4-20mA, RS-485 Modbus and optional HART communications — plus onboard Alarm 1, Alarm 2 and Fault relays — make integration into any control system straightforward. Available in ADC12 aluminium or 316 stainless steel (IP65/66) with a wide range of flammable, toxic and oxygen sensors, including long-life MPS and infrared options, the Xgard Bright is ATEX, IECEx and UL certified for use in Zone 1 and Zone 2 hazardous areas.
