Water Filter Tree presents TDS-1 is a digital water quality tester. The mellifluous design of this TDS water quality tester is perfect for personal or commercial use. This conductivity meter works with one click button and display water purity level in ppm (parts per million). For example, a TDS reading of 1 ppm would indicate there is 1 milligram of dissolved solids in 1 kilogram of water. This WFT TDS (Total Dissolved Solids) meter dissolved ionized solids, such as salts and minerals, increase the electrical conductivity (EC) of a solution. The perfect solution for instantly check water quality. Special Features: # An LCD display that shows readings # Wide measure range which is 0 ~ 4999 ppm # Backlight Features which indicate the water is drinkable or not. When the backlight is green (direct drinking water) TDS≤40ppm and red (un-direct drinking water) TDS>40ppm # Auto-off function shuts off automatically after 60 seconds of non-use to conserve batteries Specifications: Electrical conductivity: 0 ~ 9999 µS , mark symbol; overflow, display Err Measure range: 0 ~ 4999 ppm Resolution: <1000, 1ppm; ≥ 1000, 10ppm; automatic shift Temperature measurement range: 0 ~ 99°C, 32 ~ 212 °F Accuracy: ±0.1 °C Test Accuracy: ± 2% Using ambient: 0 ~ 50°C maximum relative temperature 95% Weight: 53g (include battery)
