The detector uses natural diffusion or pump-suction sampling method for gas sampling. After the gas enters the instrument through the sampling method, it is detected by sensitive components (sensors using good performance gas sensors, such as electrochemistry, catalysis, semiconductor, thermal conductivity, Optical inspection and other principles). The Sensor converts the gas concentration signal into an electrical signal, which is analyzed and calculated by the instrument's integrated circuit and intelligent processing system, and finally displays the gas concentration value or Linear dispersion in real time on the display screen, and triggers the quadruple alarm of sound, light, vibration and display when the concentration exceeds the standard.

1. Select the natural diffusion or pump sampling method according to the detection requirements and install the corresponding components. 2. Press the power button for a long time to turn it on, and the instrument will self-test. 3. By pressing the button, select the gas type and display mode to be detected (real-time data or real-time Linear dispersion). 4. Place the instrument in the environment to be tested or use a sampling pump to extract gas for detection. 5. Observe the gas concentration value or Linear dispersion displayed on the screen. 6. If you need to store data, you can perform manual storage operations. 7. After the detection is completed, press the power button to shut down. 8. Use the Type-C interface to connect the charger to charge the instrument.
* Do not use under conditions exceeding the Operating Ambient Temperature (-10 ℃~ 50 ℃) or Humidity (< 95% RH, no condensation). * Do not charge or disassemble the instrument in a flammable and explosive environment. Avoid strong impact or falling of the instrument. * Periodically calibrate the instrument to ensure detection accuracy, Sensor life is about 2 years. When calling the police, please immediately take appropriate safety measures and evacuate to a safe area. * Please use the designated 5V/1A standard charger to charge through the Type-C interface. When the instrument is not in use for a long time, please charge it regularly to keep the battery active. Do not use corrosive chemicals to clean the instrument housing. * Users are not allowed to replace the Sensor or make modifications that may affect the explosion-proof performance.
