Principle
Electrochemical sensor is used to detect gas concentration. The instrument sucks the environment gas through the built-in sampling pump (pump suction). The gas and the electrolysis liquid in the Sensor undergo oxidation or reduction reaction, generating an electrical signal proportional to the gas concentration. After the signal is processed by the microcontroller, it is converted into a concentration value and displayed. Microcontroller technology ensures Fast Response, High Accuracy and Good Stability.
Applications
It is suitable for hydrogen sulfide gas concentration detection in various industrial environments and special environments.
Standards
GB3836.1-2010 "Explosive environments - Part 1: Equipment - General requirements", GB3836.4-2010 "Explosive environments - Part 4: Equipment protected by intrinsically safe" i "
Steps
1. Check the Appearance and Filter of the Instrument before starting.
2. Press the power button for a long time to turn it on, and the instrument will self-test.
3. Enter the settings interface through the menu key as needed to customize the detection parameters (such as Alarm threshold, storage mode, etc.).
4. Place the sampling Probe in the area to be tested, and the instrument inhales the gas through the built-in pump for detection.
5. Observe the hydrogen sulfide concentration value displayed on the screen in real time.
6. After the detection is completed, press the power button to shut down or wait for the instrument to shut down automatically.
7. Historical storage data can be viewed through the Interface or on-screen menu.
Notice
• The instrument should be used in the working environment specified by the product (temperature -30~ 60 ℃, Humidity ≤ 95% RH without condensation, pressure -30Kpa~ 100Kpa).
• Avoid instrument impact or prolonged exposure to extreme environments.
• Regularly check and clean or replace the Dust Filter to ensure smooth and accurate sampling.
• The instrument has an explosion-proof mark, but it still needs to be used in the specified dangerous place.
• Please use the matching charger to charge the battery.
• If it is not used for a long time, it should be turned on regularly and the battery should be charged and discharged for maintenance.
• Sensors have a service life and need to be calibrated or replaced regularly to ensure detection accuracy.
• In case of abnormal readings or alarm, appropriate safety measures should be taken immediately and evacuated.
