Principle
The Portable VOC detector uses a pump-suction detection method with a built-in micro-sampling pump to suck the environment gas into the inside of the instrument. The gas contacts the Sensor (according to the model PID light ion principle Sensor), and the Sensor 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 EFM ultra-low power 32-bit ARM processor inside the instrument calculates and displays the real-time gas concentration value. The instrument has temperature and pressure compensation functions to ensure measurement accuracy under different environment conditions.
Applications
Monitoring gas concentrations in the environment or confined spaces and alerting
Steps
1. Boot warm-up (Warm-Up Time about 30 seconds).
2. Select the detection mode (usually detection mode or patrol mode) as needed.
3. Set alarm parameters and STEL/TWA parameters (if required) through the menu.
4. Place the sampling tube in the area to be tested, and the instrument passes the built-in pump suction sampling.
5. Observe the real-time concentration, MAX Maximum, STEL, TWA and other information displayed on the screen.
6. Use the Data storage function to record data (the storage interval is adjustable).
7. Connect to the computer through the USB interface to download or print the stored data.
8. Use self-calibration, zero or multi-point calibration functions to calibrate the instrument (if required).
9. Use the air circuit cleaning function (by adjusting the pump's gear) to clean the air circuit.
Notice
• 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 has Explosion-proof level Exia II CT4, but still needs to be used in the specified explosion-proof environment.
• Pay attention to the service life of the Sensor (about 3 years), and pay attention to the prompt of the instrument about the expiration or failure of the Sensor calibration.
• When performing zero or multi-point calibration, it needs to be operated in clean air or standard gas environment.
• When using pump suction detection, pay attention to selecting low, medium and high-grade positions according to the situation, and regularly use the automatic cleaning function to maintain the gas path.
• Avoid strong impact or immersion of the instrument in liquids, despite its waterproof and dustproof housing.
• When not in use for a long time, please store at the specified storage temperature (-30~ 70 ° C).
• When downloading or charging data, please ensure that the connection environment is safe.
• Before using the one-click factory reset function, please confirm that important data has been backed up, which will clear the user settings.
