Principle
The Portable hydrogen cyanide detector uses the pump-suction Sampling method, which actively sucks the environment gas into the instrument through the built-in micro-sampling pump. The gas contacts the built-in imported Electrochemical sensor, and the Sensor converts the concentration signal of hydrogen cyanide gas into an electrical signal. The electrical signal is amplified in two stages by a High Accuracy, Low Temperature Drift amplifier, processed by a stable power processing circuit, and finally calculated and analyzed by the EFM ultra-low power 32-bit ARM processor. 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 Operations, Industrial Safety, Emergency Response, Chemical Production
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: 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 starts to 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 setting: zero-point calibration, multi-point calibration or setting alarm parameters through self-programming function as needed.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Please read the instructions carefully before use to ensure that it is used within the instrument range (0-2000ppm) and the allowable working environment (temperature -30~ 50 ° C, Humidity 10~ 95% RH without condensation).
* The instrument is designed to be explosion-proof (Exia II CT4), but should be avoided in hazardous locations beyond the explosion-proof level.
* Regularly calibrate the Sensor to ensure detection accuracy, and the instrument will prompt when the Sensor calibration expires or fails.
* The sampling pump has an automatic cleaning function, but it is still necessary to pay attention to air cleaning after long-term use.
Avoid strong impacts or drops on the instrument to avoid damaging internal precision components.
* The data storage capacity is 300,000 group, pay attention to regularly export data to avoid insufficient storage space.
* The instrument has a built-in lithium battery, please use the matching charger to charge and avoid charging or storing in extreme temperatures.
When the instrument issues a malfunction, low power or over-limit alarm, it should be dealt with promptly.
