Online VOCs Monitor

The online VOCs monitor extracts ambient air through an air pump, and after pretreatment, uses gas chromatography or sensor technology to separate and detect the concentration of volatile organic compounds. It displays data in real time and provides alarms for exceeding limits. It is used for monitoring exhaust emissions and leakage warnings in places such as chemical industrial parks and printing workshops.
Selection
When selecting, confirm the types and measurement ranges of the substances to be detected, compare the explosion-proof rating and environmental adaptability on-site, examine the filtration capability of the sampling probe, verify the compatibility of data output interfaces, and consider the maintenance cycle and ease of calibration.
