Introduction to HQ440d Water Quality Analysis Laboratory
Water quality analysis laboratory. HQ440D host with 1-meter cable for ultrapure water pH electrode, conductivity electrode, and LDO dissolved oxygen electrode.

HQ440d Water Quality Analysis Laboratory Point
The pioneering fluorescence method for measuring dissolved oxygen (LDO) technology is easy to operate, does not require membrane replacement, and does not require maintenance.
There are a variety of intelligent IntelliCAL electrodes to choose from, which can automatically identify test parameters, calibration history, and method settings, thereby reducing errors and shortening setup time.
Convenient USB communication capability simplifies data transfer operations.
A large LCD screen with backlight illumination is convenient for reading results.
