Accurate and reliable detecting values: Tired of unreliable detecting results? Come and try our water quality detector.The device uses smart high-precision intelligent chips and high-quality titanium alloy probes to ensure detecting accuracy and stability, and becomes your trustworthy water quality detector  
  
 4-in-1 multi function upgrade: more professional TDS (total dissolved solids), EC (conductivity), and temperature (℃/℉) 4-in-1. Intelligent backlit display screen, automatic lock detecting values, no need for any buttons. automatic shutdown within 2 minutes to save power, more convenient to use  
  
 Larger backlit screen: easier to read detecting values,espically in low light or dark environments at night.Once the ppm detecting value exceeds 40ppm, the screen will turn into a red prompt. Once the ppm detecting value is below 40ppm, the screen color will remain green, that is easy to read the results  
  
 Wide range of applications: testing the purity of drinking water to ensure that the TDS value of drinking water is within the normal range, testing whether the water filter such as reverse osmosis (RO)/DI system microfiltration machine is working properly and whether the filter needs to be replaced, testing daily water, hydroponic plants (testing nutrient solution), swimming pools and spas, etc.
