Principle
The detector uses the principle of Electrochemical sensor to detect the concentration of nitrogen dioxide gas in the environment through the diffusion Sampling method. When the gas diffuses to the Sensor, the Electrochemical sensor generates an electrical signal proportional to the gas concentration, which is processed by the microcontroller and displayed on the LCD screen in real time. When the concentration exceeds the preset alarm point, the device will issue an alarm through sound, light and vibration.
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. Long press the power button to turn it on.
2. Enter the password (default 8888) to enter the work interface
3. Equipment automatically detects nitrogen dioxide concentration in the environment
4. View the concentration value in real time through the LCD screen
5. If you need to view the historical alarm records, enter the corresponding menu
6. Long press the power button to shut down after use
7. Charge in time when the power is insufficient
Notice
• Working ambient temperature range -20 ℃~ 50 ℃
• Environmental humidity of 0-95% RH, Humidity greater than 90% RH need to be equipped with filtrate drying cylinder
