Principle
The portable gas detector adopts the pump-suction Sampling method, and the built-in powerful air pump sucks the gas to be tested into the inside of the instrument. After the gas passes through the dust Filter, it enters a reasonably designed gas chamber and contacts with a specific imported electrochemistry or infrared absorption gas Sensor. The Sensor converts the gas concentration signal into an electrical signal, and processes, calculates and temperature compensation through a 24-bit ADC data collection chip and an ultra-low power 32-bit microprocessor. Finally, the gas concentration value (supporting PPM,% VOL, mg/m3, mg/L four units) is displayed on the 3.5-inch IPS industrial color screen with High Accuracy.
Applications
Various industrial environments, special environments
Standards
Explosion-proof mark: ExdII CT4 (intrinsically safe type), Protection Rating: IP65
Steps
1. Boot self-test: Turn on the power of the instrument and wait for the system self-test to complete.
2. Parameter settings: Through the full Chinese/English operation menu, customize the detection mode, storage mode, printing mode, display mode, air pump mode and other parameters according to the detection needs.
3. Sampling detection: align the instrument sampling port or place it in the environment to be tested, the built-in air pump will automatically suck the gas for detection, and the real-time concentration value is displayed on the screen.
4. Data viewing: Real-time data and stored historical data can be viewed directly on the instrument screen.
5. Data export/printing: The stored data can be transferred to an external device through the data export function, or the data can be directly printed by connecting a micro printer.
6. Maintenance of calibrating: Using the full software Automatic calibration function, Sensor calibrating up to 6 target points can be performed as needed to ensure measurement accuracy.
Notice
* Instrument working environment temperature is -30~ 60 ℃, working environment humidity ≤ 95% RH and no condensation.
* The working air pressure range of the instrument is -30~ 100Kpa, ensuring normal operation in a micro-negative pressure environment.
* Please confirm that the instrument has sufficient power before use, and the built-in 4000mA battery can ensure long standby.
* The instrument is equipped with a Dust Filter, which should be checked and replaced in time when used in harsh environments to ensure smooth sampling and Sensor life.
The instrument is marked explosion-proof (ExdII CT4), but it must still be used safely in the specified explosion-proof area.
Avoid strong static electricity or magnetic field interference in the instrument.
* Sensor calibrating, please strictly follow the operating procedures and use standard gas to ensure Measurement accuracy.
* The instrument shell is made of ABS + PC material, please avoid severe impact or drop when using.
