Overview
The Hanwei BX616 is a rechargeable diffusion detector that measures four gases simultaneously: combustible gas (%LEL), oxygen, carbon monoxide and hydrogen sulphide. Its one-button operation provides a straightforward option for daily personal monitoring.
Key features
- Four simultaneous gas readings on an LCD display
- Audible, visual and vibration alarms
- STEL and TWA alarms for toxic gases
- One-button operation and start-up self-test
- IP66 enclosure
Applications
Daily personal monitoring in industrial maintenance, wastewater treatment and petrochemical operations. The detector samples ambient air by diffusion; it does not include a built-in remote-sampling pump.
