Principle
The detector adopts the pump-suction Sampling method, and the gas to be tested is sucked into the inside of the instrument through a built-in powerful air pump. The gas passes through a reasonably designed gas chamber and comes into contact with the built-in imported electrochemistry/infrared absorption gas Sensor, which converts the gas concentration signal into an electrical signal. The microcontroller (using a new semiconductor nano process ultra-low power 32-bit microprocessor) combines a 24-bit ADC data collection chip to process and analyze the signal, and finally displays the accurate gas concentration value on the screen, and can realize data storage, printing and other functions.

Notice
* Please use it under the working environment temperature (-30~ 60 ℃) and humidity (≤ 95% RH, no condensation) specified by the instrument.
* The working air pressure range is -30~ 100Kpa, do not use in a pressure environment beyond this range.
Pay attention to the explosion-proof marking of the instrument (ExdII CT4), and comply with safety regulations in the corresponding dangerous places.
The instrument is dustproof and waterproof (IP65), but it should still be protected during use to avoid severe impact or immersion in liquids.
* Regularly calibrate according to instructions to ensure measurement accuracy.
* Please use the matching charger when charging, and note that the overcharge protection function is normal.
* When not in use for a long time, it is recommended to charge regularly to maintain battery performance.
