This advanced water quality tester  give you a complete picture of your water. The UV absorbance method measures COD, TOC, and UV275, while electrical conductivity calculates TDS, EC, salinity, general hardness, specific gravity and temperature. The device features an intelligent scoring system that changes the LCD backlight to one of four colors—Excellent, Good, Average, or Poor—so you can instantly understand your water quality at a glance.
Perfect for homeowners testing drinking water, well owners monitoring groundwater, aquarists managing saltwater tanks, or anyone who needs reliable water quality insights without leaving home.
