About This

• 🏊PH meter and salinity meter for swimming pools:Ideal pH value for swimming pools: 7.2-7.8pH, ideal salinity: 2700-3400 ppm. When the PPM value reaches 10000, it will seamlessly convert to PPT(Note: 1ppt=1000ppm=0.1% ) , easily ensuring ph meter and pool salt tester accurate measurement.
• 🌾PH tester digital,PPM meter and EC meter is ideal for hydroponics, greenhouse reservoirs and indoor plants.Ideal pH value: 5.5-6.5 pH, ideal PPM range: 800-1200 PPM, ideal EC range: 1.0-2.0 uS/cm.
• 🌱TDS meter digital water tester of Hydroponic Water:Maintain TDS between 0-500 ppm to ensure optimal performance of your hydroponic system.For optimal nutrient absorption, fill your nutrient tank with distilled, purified, or filtered water by tds meter digital water tester.
• 🌼The ph meter for water is easy to use.In addition to being suitable for hydroponics and swimming pools, it can also be used in drinking water, sewage treatment, fish tanks, aquaculture, medical and other fields.
• 💧5-in-1 Water tester Temperature meter Range: 0.0 ℃-60.0 ℃( 32.0℉-140 ℉).pH tester digital has efficient and sensitive probe,can quick response to ensure data accuracy.
