Description

[0001] Technical field: [0002] The invention relates to an air quality detector and an online calibration method. [0003] Background technique: [0004] At present, air quality detection equipment generally monitors a certain indicator. In order to evaluate the ambient air quality, multiple gas monitoring equipment need to be installed at one point; In the case of temperature, the sampled data will drop significantly. [0005] Since the life of the electrochemical probe is generally about 2 years, the replacement and calibration of the gas probe of the current equipment is cumbersome. [0006] Invention content: [0007] The object of the present invention is to provide an air quality detector and an online calibration method that are small in size and light in weight, and are convenient for the detection system to comprehensively evaluate the ambient air quality online in real time. [0008] Above-mentioned purpose realizes by following technical scheme: [0009] A kind...
