Features
1. Mainstream 8-bit micro control technology, Fast Response, High Measurement accuracy
2. Compact size, with high waterproof performance (IP65 Protection Rating)
3. Built-in 1500mA large-capacity rechargeable lithium battery, long standby
Equipped with 12864 point array LCD screen, clearly display the technical indicators and gas concentration value
5. Support Data storage function, you can view historical alarm data
6. Comes with flashlight function, convenient for dark environment operation
7. Support more than 30 Sensors, Gas detection can be customized according to customer needs
8. Alarm mode with sound, light and vibration
Principle
The detector adopts the principle of catalytic combustion Sensor to detect the concentration of target gas through diffusion Sampling method. When the gas diffuses to the Sensor, the Sensor generates corresponding signals, and displays real-time concentration data through the LCD screen after processing by the microcontroller. When the concentration exceeds the preset alarm point, the sound and light vibration alarm is triggered.
Applications
Explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels
Standards
Explosion-proof mark: Exib IIB T3 Gb, Measurement certificate number: No. 01000158
Steps
1. Make sure the device has sufficient power before turning it on and using it.
2. Turn on the device in the test environment
3. View real-time gas concentration data through the LCD screen
4. When the alarm is triggered, take corresponding measures according to the sound, light and vibration prompts
5. Charge in time after use to ensure normal use next time
