Principle
The Portable Formaldehyde detector works based on the principle of Electrochemical sensor. The instrument has a miniature sampling pump built into the instrument, which sucks the environment gas into the detection gas path. The formaldehyde molecules in the gas undergo an electrochemistry reaction inside the Sensor, generating an electrical signal proportional to the concentration. The signal is amplified and processed by a High Accuracy low temperature drift amplifier and a stable power processing circuit, and then calculated by a 32-bit ARM processor, temperature and pressure compensation. Finally, the formaldehyde concentration value is displayed on the screen in real time, and an alarm is triggered when it exceeds the standard.
Applications
Environment monitoring, confined space testing, industrial safety, indoor air mass assessment, occupational health protection
Standards
Explosion-proof certification (Exia ⅱ CT4)
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 mode: Select the 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. Start detection: Place the sampling tube in the area to be tested, and the instrument automatically inhales the gas and displays the real-time concentration.
5. Data viewing and export: You can view historical data, STEL/TWA values through the menu, and use the USB interface to connect to the computer to export data.
6. Calibration and settings: According to the needs, zero-point calibration, multi-point calibration or alarm parameters can be programmed through the menu.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
* Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 50 ° C) or Humidity (10~ 95% RH without condensation).
* Avoid strong impact or immersion of the instrument in liquid to protect its explosion-proof, waterproof and dustproof performance.
* Sensor calibration is performed regularly to ensure detection accuracy, and the instrument has a calibration expiration prompt function.
* Please check whether the sampling tube is unobstructed before use to ensure that the air path is not blocked.
When the instrument alarms, appropriate safety measures should be taken immediately and evacuated to a safe area.
When charging or transferring data, please ensure that it is carried out in a safe area.
* When not in use for a long time, please store the instrument in a drying, temperature appropriate (-30~ 70 ℃) environment.
