8. Support self-calibration, zero-point calibration, multi-point calibration functions, with temperature and pressure compensation.
9. With a key to restore factory settings, gas concentration Unit switch, self-programming alarm parameters and STEL/TWA function.
10. Provide the usual detection and patrol two detection modes, with automatic gas cleaning and fault prompt function.
Principle
The detector uses a pump-suction Sampling method, and the environment gas is sucked into the instrument through a built-in micro-sampling pump. The gas is in contact with the imported Electrochemical sensor, and the Sensor generates an electrical signal proportional to the hydrogen sulfide concentration. The signal is amplified and processed by a High Accuracy cryogenic drift amplifier and a stable power processing circuit, and analyzed and calculated by the EFM ultra-low power 32-bit ARM processor. Finally, the gas concentration value is displayed in real time on the display screen, and an alarm can be made according to the setting.
Applications
Environment Monitoring, Confined Space Operations, Industrial Safety, Petrochemicals, Wastewater Treatment, Mining, 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 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 placed in the area to be tested, 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 setting: zero-point calibration, multi-point calibration or setting alarm parameters through self-programming function as needed.
7. Shutdown: After the detection is completed, press the power button to shut down.
Notice
• Please use within the range of Ambient Temperature (-30~ 50 ℃) and Humidity (10~ 95% RH without condensation) specified by the instrument.
• Avoid long-term use in environments with strong electromagnetic interference or high concentration of corrosion gases.
Sensor calibration is performed regularly to ensure detection accuracy.
• The instrument has an explosion-proof design, but still needs to avoid disassembly or impact in hazardous locations beyond the explosion-proof level.
• After use, it is recommended to clean the air passage through the automatic cleaning function of the instrument or manually adjust the pump gear.
• When charging or data transmission, make sure to use the matching dedicated cable and adapter.
• If the instrument prompts failure or Sensor failure, please contact a professional in time to deal with it, and do not disassemble it yourself.
