Principle
Electrochemical sensor principle is used to detect gas concentration by diffusion Sampling method. When H2S gas in the environment diffuses to the Sensor, the Sensor produces an electrochemistry reaction, converts the gas concentration into an electrical signal, and displays it on the LCD screen after processing by the microcontroller, and alarms by means of sound, light and vibration.
Applications
Explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels
Standards
Exib IIB T3 Gb, IP65, Preparation No. 01000158
Steps
1. Boot up the device
2. Wait for the equipment self-test to complete
3. Observe the gas concentration value displayed on the LCD screen
4. In case of alarm, take corresponding measures according to the sound, light and vibration prompts
5. Shut down after use
6. Regular charging and maintenance
