12. Provide two detection modes of normal detection and patrol, and the gas circuit has automatic cleaning function.
Principle
The detector adopts the pump-suction Sampling method, which actively sucks the environment gas into the gas path through the built-in micro-sampling pump. The gas contacts the imported Electrochemical sensor inside the instrument, and the Sensor converts the concentration signal of nitric oxide gas into an electrical signal. The electrical signal is amplified and conditioned by a High Accuracy low temperature drift amplifier and a stable power processing circuit, and then the EFM ultra-low power 32-bit ARM processor performs data processing and analysis. Finally, the real-time gas concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard.
Applications
Environment Monitoring, Confined Space Operation Safety Testing, Industrial Safety, Emergency Response, Occupational Health Protection
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will warm up for about 30 seconds.
2. Select detection mode: Select "normal detection mode" or "patrol mode" through the menu.
3. Set the sampling pump gear: select the low, medium or high position for sampling as needed.
4. Start detection: The sampling tube is inserted into the test area, and the instrument displays the gas concentration in real time.
5. Data viewing and export: You can view historical data through the menu, or connect to a computer through the USB interface to export data.
6. Calibration and setting: Regularly carry out zero-point calibration or multi-point calibration through the menu, and can set alarm parameters according to needs.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation).
* Avoid strong impact or drop of the instrument to prevent damage to internal Sensors and circuits.
* Regularly calibrate the instrument to ensure detection accuracy, and the instrument will prompt when the Sensor calibration expires or fails.
* When used in potentially explosive environments, it is necessary to ensure that the Explosion-proof level of the instrument (Exia II CT4) meets the field requirements.
* After use, it is recommended to run the sampling pump through the high-end position to clean the gas path to avoid residual gas affecting the next measurement.
* The instrument has a built-in lithium battery, please use the matching charger when charging, and avoid charging in a high temperature environment.
If the instrument malfunctions, please do not disassemble it yourself. You should contact a professional for repair.
* When storing, please place in a drying and cool place to avoid long-term exposure to extreme temperatures (storage temperature: -30~ 70 ° C).
