4-in-1 FUNCTION - It is designed to test TDS(Total Dissolved Solids) and EC(Electrical Conductivity) of water for the purpose of purity. Temperature of water could also be examined. Measuring range: TDS: 0 - 9999 ppm; conductivity: 0 - 9999 µs/cm; temperature: 32 - 210°F/ 0 - 99°C; accuracy: ±2% F.S.
ACCURATE AND RELIABLE - This advanced meter features Automatic Temperature Compensation(ATC) which means it automatically compensates for solution temperatures within a range of 32?122?, and is equipped with a high-quality titanium alloy probe to ensure you get a accurate.
EASY AND INSTANTLY - Just stick it in about 1 inch of water, then stabilized readings will be auto-locked on LCD in seconds, TDS tester shuts off automatically after 2 minutes of non-use to conserve batteries. Features a hold function that saves measurements for convenient reading and recording.
LCD BACKLIGHT DESIGN - The meter uses low-power backlight technology to easily test water at night and in dark places. In addition, it can also be used to distinguish between drinking water and non-drinking water. Red backlight (ppm>40) means this is non-drinking water.
