Principle
The gas detector uses a pump-suction Sampling method to suck the gas to be tested into the air chamber inside the instrument through a built-in powerful air pump. The core of the instrument uses an imported electrochemistry or infrared absorption gas Sensor, combined with a new semiconductor nano-process ultra-low power 32-bit microprocessor and a 24-bit ADC data collection chip, for High Accuracy acquisition and processing of gas concentration signals. The microcontroller technology is responsible for controlling the entire measurement process, including signal conversion, temperature compensation, data calculation and display, and finally displays the gas concentration value in real time on the 3.5-inch IPS industrial color screen, and can store or output data according to the settings.
Applications
Suitable for gas concentration detection in various industrial environments and special environments.
Standards
Explosion-proof marking: ExdII CT4 (intrinsically safe type)
Steps
1. Boot preparation: ensure that the instrument has sufficient power, and install or check the dust Filter according to the detection environment.
2. Boot and self-test: Press the power button to turn it on, and the instrument will perform self-test.
3. Mode settings: Through the Chinese/English menu, set the detection mode, storage mode, printing mode, display mode, air pump mode, etc. as needed.
4. calibrating (if required): Sensor calibrating up to 6 levels of target points can be performed using the full software Automatic calibration function.
5. Start detection: place the sampling probe in the environment to be tested, and the built-in air pump will suck gas for detection.
6. Read the data: view the gas concentration (unit can be switched), temperature and humidity and other information in real time on the 3.5-inch color screen.
7. Data management: You can view historical data on the screen, transfer data through the data export function, or connect a micro printer to print data.
8. Shutdown and maintenance: shut down after testing, calibrate and maintain regularly.
Notice
• Do not use in conditions beyond the working environment temperature (-30~ 60 ℃) or humidity (≤ 95% RH, no condensation).
• The working air pressure range is -30~ 100Kpa, please do not use it in a pressure environment beyond this range.
• Instrument Protection Rating is IP65, with certain dustproof and waterproof ability, but still need to avoid long-term immersion or extreme harsh environment.
• The instrument is explosion-proof design (ExdII CT4), but still needs to be used in the specified explosion-proof environment and comply with relevant safety regulations.
• Built-in 4000mAh rechargeable battery, please use the matching charger, and note that although the overcharge protection function is available, it is still recommended to avoid overcharging for a long time.
• When calibrating, use standard gas and strictly follow the operating procedures to ensure measurement accuracy.
• If the instrument has not been used for a long time, it is recommended to turn it on regularly for inspection and charging.
• When replacing the Sensor or performing maintenance, please contact a professional or manufacturer and do not disassemble it yourself.
• Please keep the instrument properly to avoid violent impact or contact with strong static electricity and strong magnetic field interference sources.
