7. Passed the explosion-proof qualification certification, the explosion-proof level is Exia II CT4, and the shell is designed with a two-color mold that is non-slip, waterproof, dustproof and explosion-proof.
8. With self-calibration, zero-point calibration, multi-point calibration, temperature and pressure compensation functions.
9. Support one-click factory reset, gas concentration units can be quickly switched between LEL and% LEL.
10. With self-programming function, alarm parameters, STEL and TWA function parameters can be set, and two modes of normal detection and patrol are provided.
Principle
The detector adopts the pump-suction Sampling method, which actively sucks the environment gas into the gas path through the built-in micro-sampling pump. The gas contacts the imported Electrochemical sensor inside the instrument, and the Sensor converts the gas concentration signal into an electrical signal. The electrical signal is amplified by a High Accuracy, Low Temperature Drift amplifier, processed by a stable power processing circuit, and finally calculated and analyzed by the core processor based on EFM ultra-low power 32-bit ARM. The real-time hydrogen sulfide gas concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard. The instrument has the function of automatic cleaning gas circuit and fault self-diagnosis.
Applications
Petrochemicals, natural gas extraction and transportation, sewage treatment, metallurgical industry, underground coal mine, municipal pipe gallery, environment emergency monitoring, laboratory safety, 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. Mode selection: Select the normal detection mode or patrol mode through the menu.
3. Sampling settings: according to the detection requirements, adjust the suction of the sampling pump (low, medium and high) through the gear.
4. Start detection: The sampling tube is inserted into the area to be measured, and the instrument displays the gas concentration value in real time.
5. Data viewing: View real-time data, historical data, STEL, TWA and MAX Maximum through the menu.
6. Data export: Connect to a computer via USB to download or print stored data.
7. Calibration and setting: zero-point calibration, multi-point calibration or alarm parameter setting through self-programming function on demand.
Notice
* Please ensure that the instrument is fully charged before use and used within the range of Ambient Temperature (-30~ 50 ° C) and Humidity (10~ 95% RH without condensation) specified in the manual.
* Avoid long-term use in environments with strong electromagnetic interference, high concentration of dust or corrosion gases to prevent damage to Sensors or instruments.
* The air inlet of the instrument shall not be blocked by foreign objects, and the sampling tube shall be kept unobstructed to ensure the accuracy of detection.
* Perform Sensor calibration regularly. If the instrument indicates that the Sensor calibration has expired or failed, a professional should be contacted in time to deal with it.
* The instrument is designed to be explosion-proof, but must not be disassembled or repaired in hazardous locations beyond the Explosion-proof level.
* Data storage function has a capacity limit, please be careful to export data regularly to avoid overwriting.
* When cleaning the instrument, please use a soft damp cloth to wipe the shell, do not use organic solvents or soak cleaning.
