Title:
FORMALDEHYDE ELECTROCHEMICAL SENSING DETECTION APPARATUS, CALIBRATION METHOD, CALIBRATION APPARATUS, DETECTION METHOD, AND PURIFIER
Document Type and Number:
WIPO Patent Application WO/2020/173099
Kind Code:
A1
Abstract:
A formaldehyde electrochemical sensing detection apparatus, a calibration method, a calibration apparatus, a detection method, and a purifier. The method comprises: acquiring an interference factor parameter value, a sample formaldehyde concentration actual value, and a sample formaldehyde concentration detected value in environments with different interference factors; on the basis of the interference factor parameter value, the sample formaldehyde concentration actual value, and the sample formaldehyde concentration detected value, obtaining a compensation coefficient corresponding to the different interference factors; and using the acquired compensation coefficients to calibrate the formaldehyde concentration detected value in actual detection environments, thereby effectively improving the sensitivity of the response output of current sensors to environmental parameters and avoiding the influence of environmental parameter differences on detection response output results, such that an air purification product or other formaldehyde concentration removal display apparatus effectively displays the real concentration of formaldehyde in the environment.
