Principle
The portable gas detector uses a pump-suction Sampling method to suck the gas to be tested into the inside of the instrument through a built-in powerful air pump. After the gas enters a reasonably designed gas chamber, it is detected by an imported electrochemistry or infrared absorption gas sensor, which converts the gas concentration signal into an electrical signal. These signals are processed, analyzed and calculated by a 24-bit ADC data collection chip and a 32-bit microprocessor. Finally, the gas concentration value, temperature and humidity information are displayed on the 3.5-inch IPS industrial color screen, and can be stored or output according to the settings.
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. Power on: Long press the power button to start the instrument.
2. Mode settings: Select and adjust the detection mode, storage mode, printing mode, display mode, air pump mode, etc. through the menu.
3. Unit switching: Switch concentration units freely between PPM,% VOL, mg/m3, mg/L as needed.
4. Start detection: place the instrument sampling probe in the environment to be tested, and the instrument automatically pumps gas and detects.
5. Data viewing: View gas concentration, temperature and humidity values in real time on the screen, or enter the historical data menu to view the stored data.
6. Data export/printing: Connect the computer to export data through a data cable, or connect the micro printer to print data.
7.Calibrate: Automatic calibration with full software, calibrate the Sensor with up to 6 target points to ensure accuracy.
8. Shutdown: After completing the detection, press the power button to shut down.
Notice
• The working environment temperature of the instrument is -30~ 60 ° C, the humidity is ≤ 95% RH and there is no condensation. Please do not use it in an environment beyond this range.
• The working air pressure range is -30~ 100Kpa to ensure that the instrument can work normally in a micro-negative pressure environment.
• The instrument is marked explosion-proof (ExdII CT4), but it must still be used safely within the specified explosion-proof area.
• Note that the Protection Rating of the instrument is IP65, which can be dustproof and waterproof, but it is equipped with a dust filter, and maintenance should also be paid attention to when used in harsh situations.
• Built-in 4000mA rechargeable polymer battery, please use the matching charger to charge, and pay attention to the overcharge protection function.
• When calibrating, use standard gas and strictly follow the operating procedures to ensure measurement accuracy.
• The instrument has a data recovery function, but it is recommended to export important data regularly for backup.
• Avoid strong static or magnetic field interference in the instrument.
• When not in use for a long time, please charge it regularly to maintain battery performance.
