15. The detection gas circuit has an automatic cleaning function, which can automatically prompt instrument failure, Sensor calibration expiration and failure.
Principle
The detector uses a pump-suction detection method, and actively extracts environmental gas samples through a built-in micro-sampling pump. After the gas sample enters the instrument, it contacts the imported catalytic combustion Sensor inside. The Sensor works based on the principle of catalytic combustion: when flameless combustion occurs on the catalytic element on the surface of the Sensor, it will cause the component resistance change. After the change is processed by the High Accuracy low temperature drift amplifier and the stable power supply processing circuit, it is calculated by the 32-bit ARM processor and converted into the corresponding gas concentration value, which is finally displayed on the screen. The instrument has temperature and pressure compensation functions to ensure measurement accuracy in different environments.
Applications
Petrochemicals, gas transmission and distribution, fire emergency, environment monitoring, confined space operation, industrial safety
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 and STEL/TWA parameters (if required) through the menu.
4. Extend the sampling tube into the area to be measured, and the instrument passes the built-in pump suction sampling.
5. Observe the real-time concentration, MAX Maximum, STEL, TWA and other information displayed on the screen.
6. The stored data can be downloaded by connecting to the computer through the USB interface.
7. After use, the cleaning air path can be adjusted through the gear.
Notice
* Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
* Explosion-proof level of the instrument is Exia II CT4, please use it in the specified explosion-proof area.
* Regularly zero calibration and Sensor calibration to ensure measurement accuracy.
* Note that the Sensor has a lifespan of about 3 years and needs to be replaced when it expires.
Avoid strong impact or immersion of the instrument in liquids.
* Please store in an environment of -30~ 70 ° C.
Please read the instructions before use and follow the relevant safety operating procedures.
