Principle
Electrochemical sensor is used to detect gas concentration by diffusion Sampling method. Sensor signal is processed by microcontroller to display gas concentration in real time and alarm by sound, light and vibration. Data storage function is built in to record alarm history, password protection and factory reset.
Applications
Explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels
Standards
Exib IIB T3 Gb. No. 01000158
Steps
1. Power on: Press the power button to start the device
2. Check the power: ensure that the battery is sufficient and can work continuously for more than 8 hours
3. Select gas type: Select oxygen detection according to configuration (range 0~ 30% VOL)
4. Monitor gas concentration: Through diffusion sampling, the LCD screen displays the concentration value in real time
5. View historical data: Access to 1000 sets of stored alarm records
6. Alarm processing: When the concentration exceeds 19.5% LEL or 23.5% LEL, the device alarms through sound, light and vibration
7. Charging: use the matching charger to charge for 4-6 hours
8. Shutdown: Press the power button to turn off the device
Notice
• Ambient Temperature -20 ℃~ 50 ℃, Humidity 0-95% RH (non-condensing), Humidity greater than 90% RH need to be equipped with filtrate drying cylinder
Sensors have a lifespan of 2 years and require regular inspection and replacement
• Avoid use in extreme Humidity or temperature conditions to prevent accuracy
• Alarm point setting: low report 19.5% LEL, high report 23.5% LEL, do not modify at will
• Check Protection Rating IP65 before use to ensure waterproof performance
• Password protection function The default password is 8888, it is recommended to modify it to enhance security
• Be careful when restoring factory settings to avoid data loss
• Use the original charger when charging to avoid overcharging or short circuit
• Use your own flashlight in a dark environment, but pay attention to battery life
Periodically calibrate equipment to ensure measurement error ≤ +/- 5% FS
