Principle
The gas detector uses a pump-suction Sampling method to suck environment gases into the air chamber inside the instrument through a built-in powerful air pump. The gas is in contact with the built-in inlet electrochemistry or infrared absorption gas Sensor, which generates corresponding electrical signals according to the concentration of the target gas. These signals are converted into digital signals by a 24-bit ADC data collection chip and processed, analyzed and temperature compensated by an ultra-low power 32-bit microprocessor. Finally, the accurate gas concentration value (supporting PPM,% VOL, mg/m ³, mg/L multiple units) is displayed in real time on the 3.5-inch IPS industrial color screen. Instrument through the microcontroller technology implementation Fast Response, High Accuracy measurement and a variety of intelligent control functions.
Applications
Gas concentration detection in various industrial environments and special environments
Standards
Explosion-proof mark: ExdII CT4 (intrinsically safe type), Protection Rating: IP65
Steps
1. Check before starting: Ensure that the instrument has sufficient power, Sensor and Filter are installed correctly, and Appearance is not damaged.
2. Boot and self-test: Long press the power button to turn it on, the instrument will perform self-test, and the screen displays the start interface and the preheating status of the Sensor.
3. Mode setting: Enter the setting interface through the menu key, and set the detection mode, storage mode (real-time/timing), printing mode, display mode, air pump mode, etc. according to the detection requirements.
4. Calibrate (if required): Use standard gas, enter the calibrate program through the menu, and calibrate according to the prompts for zero or span (support up to 6 levels of target point calibrate).
5. Start detection: Place the sampling Probe in the environment to be tested, the built-in air pump of the instrument will automatically extract the gas for detection, and the real-time concentration value will be displayed on the main screen.
6. Data viewing and export: During or after the detection process, the stored historical data can be viewed through the menu, and the data can be exported by connecting to the computer through the data cable.
7. Print data (if required): Connect the micro printer and select print historical data or real-time data through the menu.
8. Shutdown and charging: After the detection is completed, shut down and save. When the power is insufficient, use the matching charger to charge.
Notice
• Do not use under conditions exceeding the Operating Ambient Temperature (-30~ 60 ° C) or Humidity (≤ 95% RH, no condensation).
• Operating Pressure range of -30~ 100Kpa, do not use in pressure environment beyond this range, so as not to damage the Sensor or air pump.
• The instrument has an explosion-proof mark (ExdII CT4), but it should still be avoided in hazardous locations beyond its explosion-proof level.
When calibrating, be sure to use a known concentration of standard gas and ensure a stable environment to ensure calibrating accuracy.
• The built-in battery is a polymer rechargeable battery, please use the original or designated charger to avoid overcharging and overdischarging.
• The instrument adopts a dustproof and waterproof design (IP65), but after long-term use in harsh environments (such as high dust), it is recommended to clean or replace the dust filter regularly.
• Avoid strong static electricity and magnetic field interference to the instrument, so as not to affect the Measurement accuracy.
• When using the air pump function in a micro-negative pressure environment, please pay attention to the load capacity of the pump to avoid long-term overload operation.
• The instrument shell is made of ABS + PC material, please avoid severe impact or contact with corrosion chemicals.
• When users customize setting parameters, please make sure to understand the meaning of the parameters. Wrong settings may affect instrument performance or measurement results.
