Principle
The Gas detector uses Electrochemical sensor principle to detect ozone (O3) gas concentration in the environment by diffusion Sampling method. When the gas diffuses to the Sensor, the Sensor generates an electrical signal proportional to the gas concentration. After processing by the microcontroller, the real-time concentration value is displayed on the LCD screen, and the sound and light vibration alarm is triggered when the set alarm point is exceeded.
Applications
Explosion-proof places, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels
Standards
Exib IIB T3 Gb. No. 01000158
Steps
1. Boot up the device
2. Check the gas concentration value through the 12864 point array LCD screen
3. Real-time monitoring of environment gas concentration
4. When the concentration exceeds the set alarm point, the device automatically triggers the alarm
5. Historical alarm data can be viewed through the device
6. Shut down after use
