Principle
The gas detector adopts the pump-suction Sampling method, and the gas to be tested is sucked into the air chamber inside the instrument through a built-in powerful air pump. The core of the instrument adopts imported electrochemistry/infrared absorption gas Sensor, combined with the new semiconductor nano-process ultra-low power consumption 32-bit microprocessor and 24-bit ADC data collection chip, to carry out High Accuracy acquisition and processing of gas concentration signals. The microcontroller analyzes and calculates the signal, and finally displays the gas concentration value (supports PPM,% VOL, mg/m3, mg/L and other units) and environment temperature and humidity in real time on the 3.5-inch IPS industrial color screen, and can store or output data according to the settings.
Applications
It is 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. Check whether the Appearance and accessories are in good condition before starting.
2. Press the power button for a long time to turn it on, and the instrument will self-test.
3. Set the required detection mode, storage mode, printing mode, display mode, air pump mode and other parameters through the Chinese/English menu.
4. Place the sampling probe in the environment or pipeline to be tested, and the instrument is detected by built-in pump suction sampling.
5. Read the gas concentration (unit can be switched) and temperature and humidity data in real time on the 3.5-inch color screen.
6. Historical storage data can be viewed through the on-screen menu.
7. When necessary, you can transfer data to external devices through the data export function, or connect a micro printer for data printing.
8. Turn off the machine after use and clean and maintain the instrument.
9. Periodically perform full software Automatic calibration or Sensor multi-point calibrating according to the instructions to ensure measurement accuracy.
Notice
* Do not use under conditions exceeding the working environment temperature (-30~ 60 ° C) or humidity (≤ 95% RH, no condensation).
* The working air pressure range of the instrument is -30~ 100Kpa, please do not use it in a pressure environment beyond this range.
Pay attention to the explosion-proof marking of the instrument (ExdII CT4), please use it in the specified explosion-proof area.
* The built-in battery is a 4000mA rechargeable polymer battery, please use the matching charger and pay attention to the overcharge protection function.
* The instrument adopts dustproof and waterproof design (IP65), but it should still avoid long-term immersion or extreme dust environment when using, and ensure that the dust Filter is clean.
* Sensor calibrating needs to be carried out according to the operating procedures, using the instrument's 6-level target point Adjustment to ensure accuracy.
* When using the built-in air pump in a micro-negative pressure environment, make sure that the air path is tightly connected to prevent leakage from interfering with the measurement.
Avoid strong static electricity or magnetic field interference in the instrument.
When transporting and storing, avoid severe vibrations and impacts.
Non-professional personnel should not disassemble or repair the instrument.
