Heavy Duty Tunnel Co And Visibility Detector Beefed Up Industrial Air Quality Monitor With Rs485 Digital Interface Rock Solid Traffic Safety Gear For Smoke Screening

Industrial Tunnel Air Quality And Smoke Monitor
✔️ One standalone monitor measuring CO up to 500ppm via RS485 port

This heavy duty air quality monitor tracks carbon monoxide levels and tunnel visibility in real time. Engineers install it in highway underpasses and underground garages where vehicle exhaust collects. The compact black housing screws onto walls or ceilings while delivering steady numbers to local control panels.

✅ Carbon monoxide detection range of 0 to 500 parts per million
✅ Atmospheric visibility measurement down to 0.0035 per meter
✅ Dual analog 4 to 20 milliamp outputs capped at 500 ohm impedance
✅ Standard RS485 digital serial connection for facility networks
✅ Reliable 220 volt AC power supply operating at 50 hertz

💡 How does a digital air quality transmitter improve underground parking safety protocols? Reliable gas sensors stop minor leaks from turning into dangerous pockets. - Facility managers grab live CO tracking so ventilation fans kick on exactly when needed. - Crews skip guesswork by checking clear haze numbers on main dashboards. - Building ops find the straight wired hookup handy during weekend retrofit jobs.
