Principle
The Portable hydrogen sulfide detector uses a pump-suction Sampling method with a built-in micro-sampling pump to suck the environment gas into the inside of the instrument. The gas comes into contact with the built-in imported Electrochemical sensor, which converts the gas concentration signal into an electrical signal. After the electrical signal is processed by a power processing circuit amplified and stabilized by a two-stage High Accuracy low temperature drift amplifier, it is analyzed and calculated by an EFM ultra-low power 32-bit ARM processor, and finally real-time gas concentration values are displayed on the screen. The instrument has temperature and pressure compensation functions to ensure measurement accuracy under different environment conditions.
Applications
Petrochemicals, natural gas mining and transportation, sewage treatment, metallurgical smelting, municipal pipe gallery, underground coal mine, 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 needs, select the low, medium or high Sampling flow rate.
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 settings: According to needs, zero-point calibration, multi-point calibration or alarm parameter setting can be carried out through the menu.
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 and perform boot self-test in a safe environment.
* The instrument is designed to be explosion-proof, but it is strictly forbidden to disassemble or charge in dangerous places beyond the explosion-proof level.
* Avoid severe impact or drop of the instrument to prevent damage to the Sensor and internal circuits.
* Regularly calibrate the instrument to ensure detection accuracy, and the instrument will prompt when the Sensor calibration expires or fails.
* Do not use in high concentration corrosion gas for a long time, so as not to damage the Sensor.
* Operating Ambient Temperature between -30 ° C and 50 ° C, Humidity between 10% and 95% RH (no condensation).
* The instrument has a built-in sampling pump, please ensure that the sampling pipeline is smooth to avoid blockage affecting the detection.
* Data storage is full, please export data in time to avoid overwriting.
* When not in use for a long time, please turn off the instrument and store it in a drying and cool place.
