Description
Overview
This GAOTek Hydrogen Bromide Gas Analyser It is used for on-site gas concentration detection and alarm for excessive gas concentration. It can detect the concentration of various toxic and harmful flammable gases and display the real-time concentration value and standard signal output on the spot. The main detection principles are electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photo ion. It has the advantages of stable signal, high sensitivity and precision, and the flameproof wiring method is suitable for various dangerous places.
Features
- Explosion-proof, anti-lightning, anti-static, reverse connection
- Anti-emit, EMC electromagnetic interference
- Anti-pulse surge current impact
- Three-wire system or four-wire system 4 to 20ma standard signal output
- It also has a standard bus system RS485 output (RTU format)
- The wireless transmission method can be 433, GPRS, Wi-Fi, methods
- Standard infrared remote control can be operated in dangerous situations without opening the cover
- Each unit can be switched to each other
- Automatically track the zero point to prevent drift
- It can communicate with the computer
- Monitor the concentration of the field probe in real time
