Title:
TEMPERATURE-SPECIFIC PERFORMANCE DEVIATION CORRECTION APPARATUS AND CORRECTION METHOD FOR PHOTOSENSOR DETECTING NEPHELOMETRIC TURBIDITY UNITS
Document Type and Number:
WIPO Patent Application WO/2024/024993
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for correcting temperature-specific performance deviation of a photosensor, comprising a sensing unit, which includes a plurality of photosensors, and a control unit, which: detects, by means of each of the plurality of photosensors, nephelometric turbidity unit (NTU) values at a first temperature and a second temperature for a test solution having the same NTUs; detects the difference between the NTU values according to the first temperature and the second temperature; calculates a temperature-specific NTU value difference estimate for each photosensor on the basis of the detected NTU value difference; calculates temperature-specific NTU value correction values for each of the plurality of photosensors by reflecting the temperature-specific NTU value difference estimates in a temperature-specific actual measurement value actually measured by each of the plurality of photosensors for each temperature for the test solution having the same NTUs; and corrects the NTU values of each of the plurality of photosensors according to the calculated temperature-specific NTU value correction values.
