Pool Salinity pH Tester Hydrogen Water Tester, 7 in 1 pH Salt ORP H2 TDS EC Temp Meter for Salt Water Pool, Hydrogen TDS PPM Tester for Drinking Water, pH EC ORP Meter for Hydroponic Water
7-in-1 Multi-Functional Tester: This pH Salinity Meter measures pH, salinity, hydrogen, EC, TDS, and temperature. Whether measuring drinking water, tap water, RO water, hydrogen-rich water, coffee, kombucha, apple cider vinegar, hydroponic water, freshwater aquariums, or saltwater pools, this pH meter meets your measurement needs
pH, H2, TDS, ORP Meter for Drinking Water: EZTOCH's newly launched pH, TDS, and ORP hydrogen water bottle tester in 2026 allows for one-button switching between two hydrogen detection modes (PPM/PPB). It is suitable for hydrogen-producing water bottles, hydrogen generators, hydrogen-rich water systems, H2 water generators, etc., and can simultaneously measure the ORP, pH, and TDS values of water
Spring Hydroponic pH, EC nutrient Meter: This hydroponic pH PPM meter helps you set up a hydroponic system in the spring by measuring the pH and TDS of the hydroponic basic water and the pH, EC, and ORP values of the nutrient solution in the hydroponic reservoir tank. Most hydroponic plants thrive in a slightly acidic nutrient solution with a pH of 5.5-6.5
Summer pH and Salinity Meter: In summer, you can use this salt water pool meter to measure the pH and salinity levels of saltwater pools. The ideal salinity for a saltwater pool is 2700-3400 ppm, and the pH is 7.2-7.8. The EZTOCH salinity meter helps you accurately measure the salinity level of saltwater pools
Autumn pH TDS meter: Use this meter to measure the pH and TDS values of brewed liquids such as kombucha, beer, wine, and apple cider vinegar in the fall
