Multifunctional 5-in-1 water quality tester measures pH, TDS, EC, salinity and temperature. It features high performance, tall pen shape, fast numerical stability and accurate calculation results. IP67 waterproof, this meter can still be used if dropped into the aquarium, convenient to use. Replaceable probe, automatic calibration and high reliability, easy to use. Salinity can be measured. Seawater salinity represents the ratio of total dissolved solids to the weight of sea salt in seawater. It is commonly expressed in g/kg seawater and the measurement range is 10.1 to 200 ppm. Light salt refers to light water with a salinity of less than 0.5 g/L. The measurement range is from 0.00 to 25.00% and the accuracy is from 0.01 to 5.00%, from 5.10 to 25.00%.
