Principle
The Portable VOC detector uses a pump-suction detection method to actively extract environmental gases into the instrument through a built-in micro-sampling pump. The gas is in contact with an imported catalytic combustion Sensor at the core of the instrument, which converts the gas concentration signal into an electrical signal. The electrical signal is amplified and processed by a High Accuracy cryogenic drift amplifier and a stable power processing circuit. Finally, the calculation and analysis are carried out by an EFM ultra-low power 32-bit ARM-based processor. The results are displayed on the screen in real time and alarmed according to the settings. The instrument has temperature and pressure compensation functions to adapt to accurate measurement in different environments.
Applications
Environment Monitoring, Confined Space Inspection, Industrial Safety, Emergency Response, Occupational Health
Standards
Explosion-proof level: Exia ⅱ CT4
Steps
1. Boot warm-up: Turn on the instrument power and wait about 30 seconds for Warm-Up Time.
2. Select detection mode: Select "normal detection mode" or "patrol mode" in the menu as needed.
3. Set the sampling pump gear: according to the detection environment, adjust the built-in sampling pump to low, medium or high level through the menu.
4. Detection: Place the sampling tube in the area to be tested, and the instrument will automatically sample and display real-time concentration values.
5. View data: You can view real-time concentration, MAX Maximum, STEL, TWA and other data and trend charts through the screen.
6. Data storage and export: The detection data is automatically stored, and the data can be downloaded by connecting to the computer through the USB interface.
7. Calibration and settings: Regularly use self-calibration, zero or multi-point calibration functions to maintain instrument accuracy, and can self-program alarm parameters and other functions in the menu.
8. Shut down: After the test is completed, turn off the power of the instrument.
Notice
Make sure the instrument is fully preheated before use.
• Do not use in environments beyond the range of Operating temperature (-30~ 50 ℃), Humidity (10~ 95% RH without condensation) and Air pressure (86kpa-106kpa).
• The instrument is designed to be explosion-proof (Exia II CT4), but it still needs to be used under the specified safety regulations for hazardous locations.
• Sensors are calibrated regularly to ensure detection accuracy.
• Pay attention to the cleaning of the sampling pump and gas path, which can be cleaned by using the automatic cleaning function of the instrument or by adjusting the pump gear.
• Avoid strong impact or immersion in liquids, despite the fact that the case is waterproof and dustproof.
• When not in use for a long time, please store at the recommended storage temperature (-30~ 70 ° C).
• When performing operations such as data export, please make sure to use the supporting data cable and software.
• Do not disassemble or modify the instrument yourself.
