The 5.6-inch color touch screen with intuitive GUI graphic navigation conforms to the user's operating habits and is easy for users to use.

It can measure a variety of conventional water parameters, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, chromaticity, suspended heavy metal ions, etc., with direct concentration reading, and more accurate measurement results.

It has a large-capacity storage function, built-in 5 manufacturer curves, 195 extended curves, and can store more than 5,000 experimental data, which is convenient for users to view freely.

The unique high-precision filter system makes the instrument more stable and has higher measurement accuracy.

The built-in thermal printer can print current data and stored data, saving experimental space for users.

It adopts cold light source and narrow-band interference technology, and the light source life is up to 10W hours.

With the new ARM9 chip, the instrument is more sensitive and has a larger capacity of up to 500M memory.

Support USB storage, which is convenient for users to store data.

Support users to build their own curves according to different measurement requirements, and the segmentation coefficient K can be adjusted according to measurement requirements.

Can be used with Lab-yy prefabricated reagents, greatly reducing the experimental steps, making measurements easier and data more accurate.

For power plants and boiler plants, molybdate spectrophotometry (long optical path design, lower detection limit, higher accuracy).

Test items are based on national industry standards, sulfate-"HJ T 342-2007".
