Principle
The gas detector adopts the pump-suction Sampling method, and the gas to be measured is sucked into the inside of the instrument through a built-in powerful air pump. After the gas enters a reasonably designed gas chamber, it contacts the imported electrochemistry or infrared absorbing gas Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed and calculated by a microcontroller and a 24-bit ADC data collection chip, and finally displays the exact concentration value on the screen, and can perform data storage, printing and other operations.
Applications
Industrial environment, special environment
Standards
Explosion-proof mark: ExdII CT4 (intrinsically safe type), Protection Rating: IP65
Steps
1. Turn it on to check the status of the instrument.
2. Set detection mode, storage mode, printing mode, display mode, air pump mode, etc. as needed.
3. Place the instrument sampling port in the environment or pipeline to be tested.
4. Start the air pump for sampling, and the instrument automatically detects and displays the gas concentration and temperature and humidity values.
5. Live data or historical data can be viewed on the screen.
6. Switch concentration units (PPM,% VOL, mg/m3, mg/L) as needed.
7. After the inspection is completed, you can export the data or connect the micro printer to print the data.
8. After use, shut down the machine and perform necessary maintenance on the instrument.
Notice
• Please use within the range of instrument working environment temperature (-30~ 60 ℃) and 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.
• The instrument is explosion-proof (ExdII CT4), but still needs to be used in an explosive gas environment permitted by safety regulations.
• Pay attention to calibrate the instrument regularly to ensure measurement accuracy.
• The built-in battery is a rechargeable polymer battery, please use the matching charger and pay attention to the overcharge protection function.
• The instrument is dustproof and waterproof (IP65), but after long-term use in harsh environments, it is recommended to check and clean the Dust Filter.
• Avoid strong static or magnetic field interference in the instrument.
• When using the air pump in a micro-negative pressure environment, please ensure that the air circuit connection is normal.
• The operation menu supports Chinese/English, please set it according to the user's language habits.
