[Development of a multi-spectra based portable water quality analyzer].

A novel portable multi-parameter water quality analyzer was developed based on the multi-spectra information fusion theory. The analysis method, hardware structures, working principles and software functions are described in the present paper. As a small size, rapid testing and outdoor green instrument, this analyzer can be used to measure six water organic pollution indicators, including TOC, COD, etc., through analyzing the spectra of a small amount of water sample without any chemical reagent. The practical water analysis experiments showed that the multi-spectra fusion method used by this analyzer possesses a higher measurement precision than that of the UV spectral analysis method, which is popularly used by the water quality analyzers in the market.
