10. Provide the usual detection and patrol two detection modes, automatically prompt instrument failure, Sensor calibration expiration and failure.
Principle
The Portable methane detector uses the pump-suction Sampling method, and the environment gas is sucked into the detection chamber through the built-in micro-sampling pump. The methane component in the gas has absorption characteristics for specific wavelengths of infrared light. The NDIR (non-dispersion infrared) Sensor inside the instrument calculates the concentration value of methane gas by measuring the change of infrared light Absorption intensity. The measurement results are processed by the High Accuracy amplifier and processor and displayed in real time on the screen.
Applications
Environment monitoring, confined space operation safety inspection, industrial safety inspection, gas leakage investigation, emergency rescue
Steps
1. Turn on and warm up for about 30 seconds.
2. Select the detection mode (usually detection mode or patrol mode) as needed.
3. Set alarm parameters, STEL/TWA values, etc. through the menu (if necessary).
4. Place the sampling tube in the area to be tested, and the instrument inhales the gas through the built-in pump for detection.
5. Read methane concentration value, MAX Maximum, STEL, TWA and other information in real time through the screen.
6. After the test is completed, you can use the USB interface to connect to the computer to download the stored data.
7. Regularly use the automatic cleaning function to clean the air circuit, or perform zero and multi-point calibration.
Notice
* Please use within the valid period of instrument calibration and calibrate regularly.
* Avoid use in extreme environments (beyond -30~ 50 ℃ Operating temperature, 10~ 95% RH non-condensing Humidity range).
* Note that the Operating Pressure should be kept within the range of 86~ 106kPa.
The instrument has an explosion-proof design, but it still needs to be operated in strict accordance with the specifications for the use of explosion-proof electrical equipment in hazardous areas.
Avoid strong impact or immersion of the instrument in liquids.
* When the instrument indicates that the Sensor is faulty, the calibration expires or fails, it should be dealt with in time.
When not in use for a long time, please store it properly according to the storage temperature (-30~ 70 ° C).
