We have released three self-developed water quality analysis instruments. These three instruments were developed by our R&D department based on customer feedback to meet more detailed market demands. Each one has undergone functional upgrades in the corresponding working conditions, making water quality monitoring more accurate, intelligent and simple. Here is a brief introduction to the three instruments:
The newly released portable fluorescence dissolved oxygen meter: It adopts the optical measurement principle of fluorescence quenching effect, and calculates the dissolved oxygen concentration by exciting the fluorescent dye with a blue LED and detecting the quenching time of the red fluorescence. It has the advantages of high measurement accuracy, strong anti-interference ability, and easy maintenance.

The newly released multi-parameter water quality analyzer MPG-6099DPD: It can simultaneously monitor residual chlorine, turbidity, pH, ORP, conductivity, and temperature. Its most prominent feature is the use of colorimetric method to measure residual chlorine, which offers higher measurement accuracy. Secondly, the independent yet integrated design of each unit is also a major selling point, allowing each module to be maintained separately without the need for overall disassembly, thus reducing maintenance costs.
