Principle
The gas detector adopts the pump-suction Sampling method, and the gas to be tested is sucked into the air chamber inside the instrument through a built-in powerful air pump. The core of the instrument adopts imported electrochemistry or infrared absorption gas Sensor, combined with the new semiconductor nano-process ultra-low power consumption 32-bit microprocessor and 24-bit ADC data collection chip, for High Accuracy acquisition and processing of gas concentration signals. After the signal detected by the Sensor is analyzed and calculated by the microcontroller, it is displayed on the 3.5-inch IPS industrial color screen in real time, and can be used for Data storage, processing and output. The instrument has the function of temperature compensation, which can effectively reduce the influence of Ambient Temperature on the measurement results and ensure the accuracy and Stability under different working conditions.
Applications
Suitable for gas concentration detection in various industrial environments and special environments.
Standards
Explosion-proof mark: ExdII CT4 (intrinsically safe type), Protection Rating: IP65
Steps
1. Boot preparation: ensure that the instrument has sufficient power, and install or check the dust Filter according to the on-site environment.
2. Boot and self-test: Turn on the power supply, the instrument performs self-test, and observe whether the screen display is normal.
3. Mode settings: Through the Chinese/English menu, set the detection mode, storage mode, printing mode, display mode and air pump mode as needed.
4. Unit selection: Select or switch PPM,% VOL, mg/m ³, mg/L and other concentration units in the settings.
5. Start detection: Place the sampling Probe in the area to be tested, start the air pump for sampling detection, and observe the real-time concentration display on the screen.
6. Data viewing and processing: You can directly view the historical detection data on the screen, or transfer the data through the data export function, and connect the micro printer to print the data if necessary.
7. calibrating and maintenance: Regular full software Automatic calibration or 6-level target point calibrating through the instrument menu to maintain accuracy. Store properly after use.
Notice
• Do not use the instrument under conditions exceeding the Operating Ambient Temperature (-30~ 60 ° C) and Humidity (≤ 95% RH, no condensation).
• Note that the Operating Pressure range of the instrument is -30~ 100Kpa, avoid using it in a pressure environment beyond this range.
• Although the instrument has a dustproof and waterproof (IP65) and explosion-proof (ExdII CT4) design, it is still necessary to avoid use in extremely harsh or beyond its protective capacity environment.
• The built-in battery is a large-capacity polymer rechargeable battery. Pay attention to the overcharge protection function when using it, and use the matching charger to charge.
• When calibrating, use standard gas and strictly follow the operating procedures to ensure the accuracy and linearity of the measurement.
• The instrument is equipped with a dust Filter, and the Filter should be checked and replaced regularly when used in a dust environment to prevent blockage from affecting sampling.
• Avoid strong static electricity or magnetic field interference in the instrument, so as not to affect the normal detection function.
• When using the built-in air pump in a micro-negative pressure environment, ensure that the air path is tightly connected to prevent air leakage from affecting the test results.
• The instrument stores a large amount of data, regularly exports data to prevent data overwriting, and uses the data recovery function to prevent misoperation.
