Principle
Electrochemical sensors are imported. When methane gas in the environment diffuses or enters the sensor through pumping, the sensor generates an electrical signal proportional to the gas concentration. Microcontroller technology processes and analyzes the signal to achieve accurate measurement of methane concentration and transmits the data to the receiving device through various signal output methods.
Notice
* Please ensure that the instrument is used within the specified Operating Ambient Temperature (-30~ 50 ° C) and Humidity (0~ 95% RH without condensation) range.
* Operating Pressure range is 0~ 100Kpa, do not use in pressure environment beyond this range.
Please pay attention to explosion-proof requirements when installing to ensure that the wiring meets explosion-proof standards.
The instrument has a variety of ranges to choose from. Please choose the appropriate range according to your actual testing needs.
Regularly check the zero drift and accuracy of the instrument to ensure measurement accuracy.
* The shell is explosion-proof and corrosion-proof design, but it should still be avoided for long-term use in highly corrosive environments.
* Optional Temperature and Humidity Sensor, temperature detection range -25~ 60 ℃, humidity detection range 0~ 95% RH.
