Principle
The Portable hydrogen cyanide detector uses a pump-suction Sampling method to actively suck the environment gas into the detection gas chamber through a built-in micro-sampling pump. The hydrogen cyanide (HCN) molecules in the gas react with the imported Electrochemical sensor inside the instrument to generate an electrical signal proportional to the gas concentration. The signal is amplified by a High Accuracy, low temperature drift amplifier, and then performed by a 32-bit ARM processor for analog-to-digital conversion, temperature and pressure compensation, and Data analysis. Finally, the real-time gas concentration value is displayed on the screen. When the concentration exceeds the preset alarm value, the instrument will trigger an audible and visual alarm.
Applications
Environment monitoring, confined space operation, industrial safety, emergency testing, chemical production, laboratory
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument needs to be preheated for about 30 seconds.
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, select the low, medium or high Sampling flow rate.
4. Detection: The sampling tube is inserted into the area to be tested, and the instrument screen will display the hydrogen cyanide 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 settings: According to needs, zero-point calibration, multi-point calibration or alarm parameters are set through the menu.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Please read the manual before use to ensure that it is used within the instrument range (0-5000ppm) and the allowable working environment (temperature -30~ 50 ° C, Humidity 10~ 95% RH without condensation).
* Avoid use in environments containing substances such as silica gel, silicate, lead, etc. that may poison or inhibit the Sensor.
Periodically calibrate the instrument to ensure detection accuracy.
* The instrument is explosion-proof, but it is still necessary to avoid disassembly or charging in dangerous places beyond the explosion-proof level.
* The sampling tube should be kept clean and open to avoid clogging affecting the test results.
When the instrument alarms, it should be evacuated to a safe area immediately and appropriate measures should be taken.
* When not in use for a long time, please shut down and store in a drying environment.
* It is forbidden to use corrosion liquid to clean the instrument shell.
* The built-in Sensor life of the instrument is about 3 years, and it needs to be replaced by a professional when it expires.
