Crowcon Xgard Bright XGB-A1-01-A-ZA-R-AC Fixed Gas Detector H2S-100PPM

The Crowcon Xgard Bright (Part Number: XGB-A1-01-A-ZA-R-AC) is a versatile, point gas detection transmitter manufactured by Crowcon Detection Instruments for hazardous industrial environments, oil and gas processing, water treatment facilities, and chemical plants. Housed in a heavy-duty Ex d flameproof enclosure, this multi-functional platform supports both 4-wire addressable communications and traditional 3-wire conventional analog integration. This specific configuration comes fitted with an electrochemical sensor cartridge pre-calibrated for Hydrogen Sulfide (H2S) across a 0 to 100 ppm measurement range. The device features a bright, high-contrast organic LED (OLED) screen that displays real-time gas readings, status icons, and menu navigation. Designed for single-person, non-intrusive routine maintenance, operators can perform bump testing and span calibration using a magnetic key without opening the explosion-proof enclosure. Equipped with 4-20mA analog output, RS485 Modbus digital connectivity, and three internal alarm and fault relays, it integrates cleanly into control architectures or drives local sounders and beacons directly.
