Features
1. Mainstream 8-bit micro control technology, Fast Response, High Measurement accuracy, Good Stability and Repeatability
2. Compact size, with high waterproof performance, adapt to harsh environments
3. Built-in 1500mA large-capacity rechargeable lithium battery, long standby
Equipped with 12864 point array LCD screen, clearly display gas concentration and historical alarm data
5. Support Data storage function, you can view historical alarm records
6. Bring your own flashlight for easy operation in dark environment
7. Support more than 30 kinds of Sensors, can be customized according to customer needs gas
8. Alarm modes include sound, light and vibration
Principle
Electrochemical sensor is used to detect gas concentration by diffusion Sampling method. When the gas diffuses to the Sensor, the Sensor generates an electrical signal, which is processed by the microcontroller and displayed on the LCD screen in real time. If the concentration exceeds the preset alarm point, the instrument will alarm by 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. No. 01000158
Steps
1. Power on: Press the power button to start the instrument
2. Check the battery: make sure the battery is fully charged
3. Waiting for stability: Wait for the reading to stabilize after the instrument self-test
4. Detect gas: place the instrument in the environment to be tested and observe the concentration displayed on the LCD screen
5. View historical data: View stored alarm records through the menu
6. Charging: use the matching charger to charge for 4-6 hours
Notice
• Working ambient temperature range is -20 ℃~ 50 ℃, avoid using beyond this range
• Environmental humidity is 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 calibrated or replaced regularly
• The alarm point is set to low report 5ppm and high report 10ppm, do not modify it at will
• Instrument Protection Rating is IP65, but avoid long soaking
• The default password is 8888, it is recommended to change it to protect the settings
• Please use the original charger when charging to avoid overcharging.
• Regularly check whether the function of the instrument is normal to ensure that the alarm is effective
