Environmental TVOC Detector

The environmental TVOC detector utilizes a photoionization sensor, which ionizes volatile organic compounds through an ultraviolet lamp to generate an electric current, with the current intensity reflecting the gas concentration. It is used for real-time monitoring of the total amount of organic pollutants in indoor air and industrial sites, with applications in environmental protection testing and safety production.
Selection
When selecting, focus on ensuring the detection range covers common organic compounds, with a resolution of 0.001 mg/m³, and includes data storage and alarm functions. Consider a pump-suction sampling method, a sensor lifespan of approximately 2-3 years, verify explosion-proof certification and temperature/humidity suitability, and compare maintenance costs across different brands.
