The KWS - 670 Portable Dissolved Oxygen Water Quality Sensor
The KWS - 670 Portable Dissolved Oxygen Water Quality Sensor
Overview
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.
