Principle
The Portable hydrogen sulfide detector uses the principle of Electrochemical sensor. The instrument has a built-in micro sampling pump, which sucks the gas in the test environment into the detection gas chamber. The hydrogen sulfide molecules in the gas undergo oxidation and reduction reactions on the Sensor's working Electrode, generating an electrical signal proportional to the gas concentration. After the weak signal is amplified and stabilized by a two-stage High Accuracy low temperature drift amplifier power circuit, the 32-bit ARM processor performs analog-to-digital conversion, temperature and pressure compensation and calculation, and finally displays the exact concentration value on the screen in real time, and issues an alarm according to the preset alarm value.
Applications
Environment Monitoring, Confined Space Operation Safety Testing, Petrochemicals, Wastewater Treatment, Mine Metallurgy, 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 mode: Select "normal detection mode" or "patrol mode" through the menu.
3. Set parameters: Set alarm values, STEL, TWA and other parameters through self-programming functions as required.
4. Start detection: Extend the sampling tube into the area to be tested, and the instrument automatically pumps the sampling and displays the real-time concentration.
5. Data recording: During the inspection process, the instrument automatically stores data.
6. End the detection: After the detection is completed, the data can be downloaded by connecting to the computer through the USB interface.
7. Gas path cleaning: After use, the gas path can be cleaned quickly through a high-end pump.
Notice
* Please use in the working environment specified by the instrument (-30~ 50 ℃, 10~ 95% RH without condensation).
Avoid strong impact or falling of the instrument.
* Regularly zero calibration and Sensor calibrating to ensure detection accuracy.
* Pay attention to the service life of the Sensor (about 3 years), and it needs to be replaced in time when it expires.
* When used in a potentially explosive environment, ensure that the explosion-proof marking of the instrument (Exia II CT4) meets the field requirements.
The instrument has an automatic fault prompt function, and should be dealt with in time when prompted.
When storing data, ensure that the USB connection is stable to prevent data loss.
Please clean and maintain the instrument properly after use.
