Principle
The Portable hydrogen cyanide detector uses the pump-suction Sampling method, which actively sucks the environment gas into the detection gas circuit 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 hydrogen cyanide gas into an electrical signal. The electrical signal is amplified by a High Accuracy, Low Temperature Drift amplifier in two stages, and then processed by a stable power processing circuit. Finally, the core processor based on EFM ultra-low power 32-bit ARM calculates and displays the real-time gas concentration value. The instrument has the function of automatic cleaning of the gas circuit, and can accurately compensate the gas concentration in different environments through temperature and pressure compensation algorithms.
Applications
Industrial safety monitoring, environment monitoring, confined space operation, chemical production, emergency rescue, occupational health protection
Steps
1. Boot warm-up: Press the power button to turn it on and wait about 30 seconds for the warm-up to complete.
2. Select detection mode: Select "normal detection mode" or "patrol mode" through the menu.
3. Set the sampling pump gear: According to the detection needs, set the sampling pump to low, medium or high level in the menu.
4. Detection: The sampling tube is placed in the test area, and the instrument automatically samples and displays real-time hydrogen cyanide concentration, STEL, TWA and MAX Maximum.
5. Data viewing and export: You can view historical data through the menu, or connect to a computer through the USB interface to export and print data.
6. Calibration and settings: Regularly perform zero-point calibration or multi-point calibration through the menu, and you can also enter the self-programming menu to set alarm parameters and other functions.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
* Please read the manual before use, and carry out boot warm-up and functional test in a safe environment.
* Avoid use in environments with extreme temperatures (below -30 ° C or above 50 ° C), high humidity (over 95% RH and condensing) or abnormal air pressure (beyond the range of 86~ 106kpa).
* The instrument is of explosion-proof design (Exia II CT4), but it still needs to be used in the specified hazardous place category, and it is strictly forbidden to use in environments beyond the Explosion-proof level.
* Regularly calibrate the Sensor to ensure detection accuracy. If the instrument prompts that the Sensor calibration has expired or failed, it should be dealt with in time.
* The sampling tube should be kept clean and unblocked to avoid clogging affecting the test results. After use, the gas circuit can be cleaned by the high-end position pump function.
* The instrument has a built-in rechargeable battery, please use the matching charger to charge and avoid testing during charging.
* Avoid strong impact or drop of the instrument to avoid damage to internal Sensors and circuits.
If the instrument malfunctions or the alarm is abnormal, it should be stopped immediately and a professional should be contacted for maintenance. It should not be disassembled by itself.
* When storing, it should be placed in a drying and cool place to avoid long-term exposure to high temperature or corrosion gas.
