Principle
The Portable hydrogen sulfide detector operates on the principle of electrochemistry sensing. The instrument's built-in imported Electrochemical sensor reacts with the target gas (H2S) to generate an electrical signal proportional to the gas concentration. The signal is amplified and processed by a two-stage High Accuracy, Low Temperature Drift amplifier. Data analysis and compensation calculations (including temperature and pressure compensation) are performed by a high-performance 32-bit ARM microcontroller. Finally, the accurate concentration value is displayed on the screen and an alarm is triggered when the concentration exceeds the standard.
Applications
Petrochemicals, natural gas extraction and treatment, sewage treatment, metallurgical industry, 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 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 H2S concentration value in real time.
5. View data: You can view real-time concentration, MAX Maximum, STEL, TWA values and historical trend graphs through the menu.
6. Data export: Connect to the computer via USB and download the stored test data.
7. Calibration and setting: zero-point calibration, multi-point calibration or alarm parameter setting through self-programming function on demand.
8. Shut down and maintenance: shut down after the detection, the instrument has the function of automatic cleaning gas circuit, and prompts the Sensor status.
Notice
* Please make sure that the instrument is fully charged before use, and use it within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
* Before entering the potentially hazardous area, turn it on in the safe area and confirm that the instrument is working properly and the Sensor is valid.
* Avoid severe impact or drop of the instrument to prevent damage to the Sensor and internal circuits.
* Regularly calibrate the instrument according to the instructions to ensure detection accuracy.
When the instrument alarms, it should be evacuated to a safe area immediately and the cause should be identified.
* Do not use in an environment with high concentration corrosion gas for a long time to avoid damage to the Sensor.
* Although the instrument housing is protective, it should still avoid prolonged immersion in water or exposure to extreme environments.
* Data storage card or USB connection operation, please ensure that the instrument is in a safe environment and follow the operating procedures.
* The service life of the instrument Sensor is about 3 years, and a professional should be contacted to replace it in time when it expires or fails.
