Principle
The Portable Hydrogen Chloride Detector uses the pump-suction Sampling method, which draws environment gases into the detection gas path through a built-in micro-sampling pump. The gas comes into contact with an imported Electrochemical sensor inside the instrument, which converts the concentration signal of the hydrogen chloride gas into an electrical signal. The electrical signal is amplified by a High Accuracy, Low Temperature Drift amplifier, processed by a stable power processing circuit, and finally calculated and displayed by the core processor based on the EFM ultra-low power 32-bit ARM. The instrument has temperature and pressure compensation to correct for the impact of environmental factors on the measurement results.
Applications
Environment monitoring, confined space operation safety inspection, industrial process control, emergency accident handling, occupational health and safety
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 as needed for sampling and cleaning the gas path.
4. Detection: The sampling tube is placed in the environment to be tested, and the instrument displays the hydrogen chloride concentration value, STEL, TWA and MAX Maximum 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 settings: zero-point calibration, multi-point calibration or self-programming alarm parameters through the menu.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
* Please make sure that the instrument is fully charged before use, and use it within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
* Avoid long-term use in environments containing substances such as silica gel, silicate, lead, etc. that may poison the Sensor.
* The instrument has an automatic fault prompt function, and should be dealt with in time when a fault occurs, Sensor calibration expires or fails to prompt.
* When performing calibration operations, a standard gas of known concentration should be used and zero-point calibration should be carried out in a clean air environment.
* The instrument is designed to be explosion-proof, but the battery must not be removed or replaced in hazardous locations beyond the explosion-proof level.
* Regularly use the automatic cleaning function of the instrument or manually adjust the pump gear to clean the sampling gas path to ensure the accuracy of detection.
* When not in use for a long time, it should be shut down and stored in a drying environment. Temperature range is -30~ 70 ℃.
* Do not use corrosion cleaning agents to wipe the instrument case.
* Instrument readings are for reference only, if there is any doubt about the measurement results, please use standard gas for verification.
* When replacing Sensors or undergoing major repairs, please contact a professional for operation.
