Introduction:
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.
Use imported brand gas sensors (Honeywell, Japan Nemoto, British CITY, British Alpha, British Dynament, Swiss Membrapor, etc.) gas sensors,
The main detection principles are: electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoion. 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-EMI, EMC electromagnetic interference, anti-pulse surge current impact.
• Comply with the latest national standards and obtain the CPA measuring instrument type approval certificate, explosion-proof certification and other qualifications.
•Three-wire system or four-wire system 4-20mA standard signal output, voltage output, 2 sets of relay switch values.
• It also has a standard bus system RS485 output (RTU format), optional integrated sound and light alarm.
• Optional with extra charge wired transmission, LAN, Internet, wireless transmission (2 kilometers, 5 kilometers, unlimited distance).
• The wireless transmission method can be 433, GPRS, WIFI, and other methods.
• The standard infrared remote control can be operated in dangerous situations without opening the cover, and the remote control distance is 15 meters, which is simple and practical
• Each unit can be switched to each other, automatically track the zero point to prevent drift, multi-level calibration.
• It can communicate with the computer, monitor the concentration of the field probe in real time through the upper computer on the computer, and store, analyze and print the data on the computer.
