Using the "persulfate + heating + UV" oxidation technology, the recovery rate of organic carbon is high (more than 98%), and the actual water sample test is more accurate. In addition, TOC is more representative than COD in the characterization of organic pollution. Compared with COD,TOC has no secondary pollution. Through independent patented technology, most of the light emitted by bacteria (more than 70%) can be collected into the instrument for subsequent light inspection, and the instrument has high measurement sensitivity and strong stability.

Using the proprietary "photon counting" technology, the measurement sensitivity is greatly improved and the background noise is effectively reduced. The influence of water sample turbidity or blackness or color on measurement is effectively solved.

A single measuring unit is used to measure blank samples and actual water samples. Compared with two measuring units, it has the characteristics of stable measurement, simple structure and easy maintenance under the premise of ensuring the measuring cycle of about 1 hour.

It meets the 1S011348 standard and detects more than 5000 kinds of toxic substances, including heavy metals, pesticides, detergents, herbicides, etc. Using a number of independent patents and proprietary technologies, the bacterial luminescence method has successfully solved many technical problems in the field of online water quality monitoring, such as environmental temperature change, turbidity and background absorption, luminescence and light detection instability, short life of bacterial solution and large use of bacteria.
