Principle
The gas detector uses a pump-suction Sampling method with a built-in powerful air pump to suck the gas to be tested into the inside of the instrument. The gas passes through a reasonably designed gas chamber and contacts the imported electrochemistry/infrared absorbing gas Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed and calculated by a 24-bit ADC data collection chip and an ultra-low power 32-bit microprocessor, and finally displays the accurate concentration value in real time on a 3.5-inch IPS industrial color screen. The instrument has a temperature compensation function to cope with changes in the environment and ensure the accuracy of measurement results.
Applications
Various industrial environments, special environments
Standards
Explosion-proof mark: ExdII CT4 (intrinsically safe type), Protection Rating: IP65
Steps
1. Boot inspection: Make sure that the instrument has sufficient power, and turn it on for self-inspection.
2. Mode settings: According to the detection requirements, set the detection mode, storage mode, printing mode, display mode, air pump mode, etc. in the menu.
3. Calibrate and compensate: Use the full software Automatic calibration function to calibrate up to 6 levels of target points if necessary, and ensure that the temperature compensation function is turned on.
4. Sampling detection: The sampling probe is placed in the environment to be tested, the built-in air pump starts to work, and the instrument automatically detects and displays the gas concentration (the unit can be freely switched).
5. Data recording: The instrument can store data in real time or at regular intervals, with a maximum of 30,800 sets of data stored in a single channel.
6. Data viewing and export: View historical data visually on the screen, and export data through the corresponding interface.
7. Data printing: Connect the micro printer to print the detection data.
8. Shutdown and Maintenance: Shut down after testing, clean the Dust Filter regularly, and charge the battery.
Notice
• The working environment temperature of the instrument is -30~ 60 ° C, the humidity is ≤ 95% RH and there is no condensation, the working air pressure range is -30~ 100Kpa, please do not use it in an environment beyond the range.
• The instrument is marked explosion-proof (ExdII CT4), but it must still be operated under the specified safety regulations for hazardous locations.
• Built-in 4000mA rechargeable polymer battery, please use the matching charger and pay attention to the overcharge protection function to avoid improper charging.
• When sampling, make sure the gas path is unobstructed and the dust Filter is clean to ensure sampling efficiency and Sensor life.
• The instrument adopts dustproof and waterproof design (IP65), but it is not absolutely sealed, and should avoid long-term immersion or strong water flow Impact.
• When calibrating, use standard gas and operate in a safe environment to ensure calibrating accuracy.
• Avoid instrument from strong static electricity and magnetic field interference to prevent affecting Measurement accuracy.
• The instrument shell is made of ABS + PC material, please avoid impact and fall to prevent damage.
• If it is not used for a long time, it is recommended to turn it on regularly and charge and discharge the battery for maintenance.
