Portable multi parameter water quality analyzer

Brand:Tengyuyi^®

model:DSA

characteristic：

1.The integration of photometry, electrode method, and titration method has been achieved through the use of self-developed speed measurement improvement technology. One instrument can detect multiple indicators, bringing great convenience to users;

2.The light source adopts long-life light-emitting diodes and pulse power supply, with a long service life10Ten thousand hours, better stability of light source;

3.The colorimetric system adopts an integrated photoelectric sensor with no movable parts, and the instrument has stronger seismic and moisture resistance performance;

4.Large LCD display screen, directly displaying test data;

5Light touch micro buttons, moisture-proof and durable, single key single function design, quick and convenient operation;

6.The sample chamber is a square colorimetric cell to avoid errors caused by uneven walls of circular colorimetric tubes, resulting in higher measurement accuracy;

7.Equipped with specialized testing reagent kits for finished products, greatly reducing reagent preparation time, increasing testing efficiency, and simplifying operation;

8.Randomly equipped with sample collection and preprocessing equipment, specialized detection reagent kits, and other accessories, fully matched and easy to use;
