YW-662 is an instrument for detecting TDS, EC(conductivity value) and temperature. It can be used in industries, laboratories, agriculture, and environmental protection. The electrode probe of YW-662 is made of titanium alloy, which has the characteristics of high sensitivity and corrosion resistance. In addition, one button of YW-662 corresponds to one function, and the operation is very simple. User only need to put the electrode probe into the measured solution while measuring to measure the TDS, conductivity and temperature quickly and accurately .
