Principle
The Portable hydrogen sulfide detector works based on the principle of Electrochemical sensor. The sensor converts the concentration of hydrogen sulfide gas in the environment into an electrical signal, which is amplified and processed by the built-in High Accuracy low temperature drift amplifier and stable power processing circuit. The core of the instrument uses an EFM ultra-low power 32-bit ARM processor to analyze and calculate the processed signal. Finally, the gas concentration value is displayed in real time on the display screen, and the sound and light alarm is triggered according to the preset alarm parameters. The built-in micro sampling pump actively sucks the gas to be tested into the detection gas path to ensure a rapid Response.
Applications
Petrochemicals, natural gas mining and transportation, sewage treatment, metallurgical industry, underground coal mine, municipal pipe gallery, environment monitoring, emergency rescue, confined space operation
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 environment, set the sampling pump to low, medium or high in the menu.
4. Detection: The sampling tube is inserted into the area to be tested, and the instrument will display the hydrogen sulfide concentration in real time.
5. Data viewing and export: View historical data through the menu, and use USB to connect to a computer to export or print data.
6. Calibration and settings: Regularly perform zero-point calibration or multi-point calibration through the menu, and can set alarm values, STEL, TWA and other parameters according to needs.
Notice
* Please read the instructions carefully before use to ensure that it is used within the instrument range (0-20000ppm) and the allowable working environment (temperature -30~ 50 ° C, Humidity 10~ 95% RH without condensation).
* Avoid long-term use in environments containing substances such as silica gel, silicate, lead, etc. that may poison the Sensor.
* The instrument has the explosion-proof mark Exia II CT4, but it needs to be used in the specified explosion-proof environment, and it is strictly forbidden to disassemble or charge in dangerous places beyond the explosion-proof level requirements.
* Regularly calibrate the instrument to ensure detection accuracy, and the instrument will prompt the Sensor calibration to expire or fail.
* The built-in sampling pump gas path has an automatic cleaning function. After detecting high concentration gas, it is recommended to run the instrument in clean air to clean the gas path.
* Data storage capacity of the instrument is large, it is recommended to export data regularly to prevent overwriting.
Avoid strong impacts or drops on the instrument to avoid damage to the Sensor or internal circuitry.
* When not in use for a long time, please shut down and store in a drying environment.
