Principle
The gas detector uses a pump-suction Sampling method with a built-in powerful air pump to suck the gas to be measured into the inside of the instrument. When the gas passes through the Sensor (such as electrochemistry or infrared absorption Sensor), the Sensor generates a corresponding electrical signal according to the gas concentration. The microprocessor (using a 32-bit ultra-low power chip) and a 24-bit ADC data collection chip process and analyze the signal, and finally display the gas concentration value in real time on the 3.5-inch IPS industrial color screen, and can store, print and export data.
Applications
Various industrial environments, special environments
Standards
Explosion-proof mark: ExdII CT4 (intrinsically safe type), Protection Rating: IP65
Steps
1. Turn on the instrument.
2. Adjust the detection mode, storage mode, printing mode, display mode, air pump mode, etc. as needed.
3. Use the pump-suction Sampling method for gas sampling of the test environment.
4. Read the gas concentration value in real time on the 3.5-inch IPS color screen, and can freely switch between PPM,% VOL, mg/m3, mg/L four units.
5. Historical data records can be viewed on the screen.
6. Export data or connect a micro printer to print data as needed.
7. Shut down after use.
Notice
* Working environment temperature: -30~ 60 ℃, working environment humidity: ≤ 95% RH, no condensation.
* Working air pressure range: -30~ 100Kpa.
* The instrument is marked explosion-proof (ExdII CT4), but still needs to be used in the specified safe environment.
* Note that the Protection Rating of the instrument is IP65, which can be used in dustproof and waterproof applications, but the dust filter needs to be properly installed and maintained.
* Periodically calibrate using the instrument's full software Automatic calibration and 6-level target point Adjustment to ensure measurement accuracy.
* Built-in 4000mA rechargeable polymer battery, pay attention to the overcharge protection function, and charge as required.
The instrument has a data recovery function, but it is recommended to export important data regularly for backup.
