Functional features:

Ø1.approveFully automatic operation,Sample testing can be carried out continuously or with a fixed sample interval set, and the instrument can spontaneously and periodically measure samples on its own；

Ø2. It can be fully automated for cleaning, and can be manually cleaned at any time or after setting a fixed cleaning intervalSpontaneous periodic cleaning;

Ø3.Equipped with fully automatic calibration function,Calibration can be manually performed at any time or the instrument can calibrate itself after setting a fixed calibration cycle；

Ø4. Stable operation，No need for frequent maintenance,Maintenance interval>1 month, with each maintenance lasting approximately 30~60minute;

Ø5.Adequate memory,Storable20000 pieces of data,justNo loss in case of power failure, automatically overwrite the earliest data when fully stored（Customizable expansion of memory）；

Ø6Adopting TFT true color touch screen, 7-inch large screen, 70000 colors, 800 * 480 resolution, the instrument's working status is clear at a glance；

Ø7. The instrument reserves a printer interface, which can be customized and equipped with industrial micro printers (optional);

Ø8. The instrument is equipped with a preprocessing system that can achieve functions such as self-cleaning, blowback, and precision filtration to avoid suspended particles blocking the pipeline.
