Abstract

The present invention relates to a photoelectric dynamic detection device for fluid and its application in contamination test. Said device includes two portions of fluid measuring chamber whose two ends are equipped with light transmission window respectively and optical measurement system. The optical measurement system includes light source, chopper, lens, filter, optical sensor and signal amplifier. It is characterized by that two ends of said fluid measuring chamber are respectively equipped with a buffer chamber, on every buffer chamber a clean fluid inlet is set respectively, two ends of fluid measuring chamber are respectively equipped with a clean fluid and a detected fluid outlets, between two outlets a detected fluid inlet is set.

Description

technical field [0001] The invention relates to a fluid photoelectric dynamic detection device and its application in poison exposure test. Background technique [0002] At present, when measuring the content of certain substances in air (gas) or liquids online according to the Lambert-Beer law, most of the samples to be tested are sucked into an optical measurement chamber, and its structure is roughly composed of two parts: one is composed of The fluid measurement chamber with optical glass light-transmitting windows at both ends, and the photoelectric measurement system composed of light source, optical chopper, lens, filter, optical sensor and signal amplifier. However, when the measured sample enters the measurement chamber, the measured sample tends to accumulate inside the two light-transmitting window glasses at the entrance and exit of the optical path of the optical measurement chamber, affecting the passage of light and causing inaccurate measurement. For example...
