Principle
The detector works based on the principle of Electrochemical sensor. The electrolysis liquid in the Sensor undergoes oxidation and reduction reaction with the target gas (hydrogen peroxide), generating an electrical signal proportional to the gas concentration. The weak signal is amplified and processed by the built-in two-stage High Accuracy and low temperature drift amplifier, and then calculated and compensated (including temperature and pressure compensation) by the core processor of the instrument (32-bit ARM). Finally, the accurate gas concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard. The built-in micro sampling pump actively sucks the environment gas into the detection gas path to ensure fast Response.
Applications
Chemical production, Pharmaceutical industry, Food processing, Medical disinfection, Water treatment, Laboratory safety, Environment monitoring, Confined space operation
Steps
1. Boot warm-up: Press the power button for a long time to turn it on, and the instrument will self-test and 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, set the sampling pump to low, medium or high level in the menu.
4. Detection: The sampling tube is inserted into the area to be measured, and the instrument screen will display the hydrogen peroxide gas concentration value in real time.
5. Data viewing and export: You can view the stored data through the historical data menu, or connect to the computer through the USB interface to export the data.
6. Calibration and settings: Regularly perform zero-point calibration or multi-point calibration through the menu, and you can also enter the settings menu to adjust the alarm value, STEL/TWA and other parameters.
Notice
* Do not use in environments beyond the -30~ 50 ℃ Temperature range or 10~ 95% RH (non-condensing) Humidity range for long periods of time.
* Avoid strong impact or drop of the instrument to prevent damage to the Sensor and internal circuits.
* Regularly calibrate the instrument to ensure the accuracy of the test data. Please refer to the relevant specifications or usage for the specific calibrating period.
The instrument is designed to be explosion-proof, but it is strictly forbidden to remove or replace the battery in a dangerous location.
* After use, it is recommended to clean the gas path with clean air, especially after detecting high concentration of gas.
Please use the USB data cable that comes with the instrument for charging and data transmission.
* Sensor life is about 3 years, expiration or failure need to contact a professional replacement.
* When the instrument is stored, it should be placed in a drying, non-corrosion gas environment. Temperature range is -30~ 70 ℃.
