The online VOC detector adopts the principle of ultraviolet photoionization detection, which has the characteristics of high accuracy and good stability. Combined with temperature and humidity compensation algorithms, it effectively reduces the interference of water vapor and environmental factors. At present, this signal is widely used in industries such as environment, petroleum, chemical, pharmaceutical, and spraying, and has gained a good reputation.
