Principle
The Portable carbon monoxide detector uses the principle of Electrochemical sensor. The instrument has a miniature sampling pump built into the instrument, which sucks the gas in the environment into the detection gas chamber. The carbon monoxide molecules in the gas undergo electrochemistry inside the Sensor, generating an electrical signal proportional to the gas concentration. The signal is amplified and processed by a High Accuracy, Low Temperature Drift amplifier, and then calculated and compensated by a 32-bit ARM processor (including temperature and pressure compensation). Finally, the accurate carbon monoxide concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard.
Applications
Environment monitoring, confined space operation safety inspection, industrial safety inspection, emergency rescue
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 Sampling flow rate as needed.
4. Detection: The sampling tube is inserted into the area to be measured, and the instrument automatically samples and displays the real-time concentration.
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
* The instrument should be used within the range of Ambient Temperature -30~ 50 ℃ and Humidity 10~ 95% RH (non-condensing).
* Avoid long-term use in environments with strong electromagnetic interference, high dust or high corrosion gas concentrations.
* Regularly calibrate the Sensor to ensure detection accuracy. The instrument has an automatic prompt function for calibration expiration.
* The sampling pump has an automatic cleaning function, but it is recommended to manually clean the sampling line after use in a polluted environment.
The instrument is designed to be explosion-proof, but it is strictly forbidden to remove or replace the battery in a dangerous location.
* When storing, it should be placed in a drying environment of -30~ 70 ° C.
* Please confirm that the instrument has sufficient power before use, and check whether the sampling tube is unobstructed and not damaged.
When the instrument alarms, it should be evacuated to a safe area immediately and the cause should be identified.
