Principle
Electrochemical sensor is used to detect gas concentration by diffusion Sampling method. When the target gas comes into contact with the Sensor, an electrochemistry reaction occurs. The instrument processes the signal through a microcontroller, displays real-time concentration data on the LCD screen, 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. Power on: Press the power button to start the instrument
2. View data: View real-time gas concentration and historical alarm records through 12864 point array LCD screen
3. Alarm processing: When the concentration exceeds the set alarm point (low 5ppm, high 10ppm), the instrument will alarm through sound, light and vibration
4. Data storage: the instrument automatically records 1000 sets of alarm data
5. Charging: use the matching charger to charge for 4-6 hours
6. Password operation: If you need to modify the settings, enter the default password 8888 for relevant operations
Notice
* Ambient Temperature -20 ℃~ 50 ℃, Humidity 0-95% RH (non-condensing), Humidity greater than 90% RH need to be equipped with filtrate drying cylinder
* Sensor life is 2 years and needs to be replaced regularly
* Avoid prolonged use in extremely harsh environments
* Please use the original charger when charging, Charging time 4-6 hours
* The instrument weight is about 130g (excluding portable Accessories), pay attention to anti-drop when carrying
* The alarm point is set to low report 5ppm and high report 10ppm, please do not modify it at will
* Instrument Protection Rating is IP65, but it is still necessary to avoid long-term immersion in water
* Please confirm the battery level before use to ensure Continuous Operating Time of more than 8 hours
