3. Equipped with a 3.5-inch TFT full-color display, it supports Chinese and English graphical menus and real-time detection of trend analysis charts.
4. With large-capacity Data storage function, it can store up to 300,000 sets of data, and the storage interval is adjustable.
5. Built-in long-life imported micro sampling pump, support low, medium and high three-speed adjustment, with automatic cleaning gas circuit function.
6. In line with explosion-proof certification, 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.
7. Support USB interface for high-speed data transmission, allowing you to download and print data.
8. With self-calibration, zero-point calibration, multi-point calibration, temperature and pressure compensation functions.
9. Provide one key to restore factory settings, quick switching of gas concentration units, self-programming to set alarm parameters and STEL/TWA functions.
10. Support two detection modes of normal detection and patrol, and have the function of automatic prompt of fault, Sensor expiration and failure.
Principle
The detector works based on the principle of electrochemistry sensing. The built-in micro-sampling pump sucks the environment gas into the instrument, and the gas reacts electrochemically with the electrolysis solution in the Sensor to generate an electrical signal proportional to the hydrogen sulfide concentration. After the signal is amplified by a High Accuracy, Low Temperature Drift amplifier and a stable power supply circuit, it is analyzed and calculated by a 32-bit ARM processor. Finally, the real-time gas concentration value is displayed on the screen, and an alarm is triggered when the concentration exceeds the standard.
Applications
Petrochemicals, natural gas extraction and transportation, sewage treatment, metallurgical smelting, municipal pipe gallery, confined space operation, environment monitoring, emergency rescue, industrial safety inspection
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 environment, set the sampling pump to low, medium or high in the menu.
4. Start detection: The sampling tube is inserted into the area to be measured, and the instrument automatically samples and displays the H2S concentration in real time.
5. Data viewing and export: View historical data, STEL/TWA values through the menu, or export data by connecting to a computer through the USB interface.
6. Calibration and settings: Regularly perform zero or multi-point calibration through the menu, and can set parameters such as Alarm threshold and unit.
7. Shutdown: After the detection is completed, press the power button for a long time to shut down.
Notice
* Please read the instructions before use to ensure that it is used under the instrument range (0-7000ppm) and specified environmental conditions (temperature -30~ 50 ℃, Humidity 10~ 95% RH without condensation).
* Avoid use in environments with strong electromagnetic interference, high corrosion gases, or substances that may damage the Sensor.
* Periodic Sensor calibration to ensure measurement accuracy, the instrument will prompt calibration expired or Sensor failure.
Instruments are explosion-proof, but must not be disassembled or charged in hazardous locations beyond the Explosion-proof level.
* The sampling tube should be kept clean and unblocked to avoid blockage affecting the sampling. After use, the cleaning function that comes with the instrument can be used to clean the air passage.
* The instrument has a built-in rechargeable battery, please use the matching charger to charge in a safe place.
If the instrument alarms, evacuate to a safe area immediately and identify the cause.
* Please store in a drying and cool place (-30~ 70 ℃) to avoid direct sunlight and mechanical Impact.
