KWS-670 Portable Optical Dissolved Oxygen Meter Introduction KWS-670 adopts the advanced fluorescence quenching principle to
measure the dissolved oxygen concentration in water bodies without
any loss. It has the advantages of being pollution-free, having a
long service life, good stability, and low maintenance difficulty. This product is convenient for users to carry around, enabling them
to monitor dissolved oxygen (with barometric pressure and salinity
compensation) and temperature on-site. It can also calibrate the
dissolved oxygen measurement probe. The display uses a liquid crystal display, which provides clear
readings and is easy to use. It is powered by a built-in lithium
battery, eliminating the need to replace the battery, and it can
conduct continuous measurements on-site.
