Description

Xgard Bright

 

CROWCON XGARD Bright Fixed Gas Detector is a versatile detector offering flammable and toxic gas detection and oxygen monitoring, while providing ease of operation and reduced installation costs. Choose from durable sensor options to suit your needs, such as MPS (10+ years), Long-life O2 (5 years) and IR sensors (10+ years) to prevent frequent sensor replacements and minimise operational expenses.

CROWCON XGARD Bright Fixed Gas Detector lowering the cost of installation, the 4-wire addressable implementation drastically reduces cabling requirements. The large OLED display allows users to easily work with Xgard Bright during install, calibration and routine maintenance without the need to open the housing. Providing analogue 4-20mA and RS-485 Modbus signals as standard, Xgard Bright comes with an Alarm and Fault relay as standard as well as optional HART communications.
