Principle
The gas detector uses natural diffusion for gas detection. The gas enters the instrument through natural diffusion and reacts with the built-in industrial-grade Sensor, which converts the gas concentration signal into an electrical signal. The microcontroller processes and analyzes the electrical signal, and finally displays the gas concentration value in real time on the LCD screen. When the concentration exceeds the preset alarm point, the instrument will issue an alarm through Light Emitting Diode, sound and vibration.
Applications
Petroleum, chemical industry, environmental protection, metallurgy, refining, gas transmission and distribution, agriculture, explosion-proof places, toxic gas leakage rescue, underground pipelines, mines, power plants, tunnels, tunnels
Standards
GB3836.1 - 2010 "Explosive environment Part 1: General requirements for equipment", GB3836.4 - 2010 "Explosive environment Part 4: Equipment protected by intrinsically safe" i ", GB12358 - 2006" General technical requirements for workplace environment Gas detection alarms ", GB15322.3 - 2019" Combustible gas detectors Part 3: Portable combustible gas detectors for industrial and commercial use ", JJG693 - 2011" Combustible Gas detection alarm verification regulations ", JJG365 - 2008" electrochemistry oxygen detector verification regulations ", JJG695 - 2019" Hydrogen sulfide gas detector verification regulations ", JJG915 - 2008" Carbon monoxide detection alarm verification regulations "
Steps
1. Power on: Long press the power button to start the instrument.
2. Self-test: Conduct self-test after the instrument is started to observe whether the display and status indicator are normal.
3. Detection: The instrument is placed in the environment to be tested and the gas concentration is detected by natural diffusion.
4. Reading: Real-time gas concentration data (in ppm) is read on the LCD screen.
5. Alarm Response: When the concentration exceeds the standard, the instrument will issue sound and light vibration alarm, and corresponding measures need to be taken according to the safety procedures.
6. Shutdown: Long press the power button to turn off the instrument.
7. Charging: When the battery is low, use the matching charger to charge the built-in lithium battery, which lasts about 4-6 hours.
Notice
* Do not use in an environment that exceeds the specified temperature (-10~ 55 ° C) and humidity (< 95% RH without condensation).
* The instrument is designed to be explosion-proof (ExibIICT4Gb), but it is still necessary to avoid abuse in extremely dangerous environments.
* Alarm point can be manually set as needed, different gas default alarm point is different, please do not change at will.
* Sensor life is about 2 years, the actual life depends on the specific Operating Environment, requires regular maintenance or replacement.
* Please use the original or designated charger when charging, and ensure the safety of the environment.
* The continuous Operating Time of the instrument is not less than 8 hours, please pay attention to the power prompt and charge it in time.
Avoid severe impact or immersion of the instrument in liquids to prevent damage.
Periodically calibrate instruments according to relevant verification procedures to ensure measurement accuracy.
