Dual LCD display, large screen LCD backlight display, 240 * 128 dot matrix,

Chinese operating interface, user-friendly programming.

Provide software support

Provide supporting software that can connect to a computer to view, store, and print relevant measurement data

And measure the curve.

Comes with printing function

The rapid water quality analyzer comes with a thermal printer that can directly print measurement data and historical data.

Mass storage

Can store 30000 historical records, with power-off protection design to ensure that the instrument is not damaged

And data records are not lost.

Automatic calibration system

The calibration mode from 1 o'clock to 7 o'clock automatically calculates slope, intercept, and correlation coefficient, with high measurement accuracy.
