5-in-1 Digital Water Tester (pH, Temperature, EC, TDS and Salinity) — pH Meter for Water with Backlit LCD Screen — Testing Kit for Drinking Water, Wine, Swimming Pools and Spas.

5-in-1 pH Meter: This multi-parameter water quality tester integrates five distinct analysis functions—Salinity, TDS, EC, pH, and Temperature—seamlessly combined in a single device. It not only meets your various water quality monitoring needs but also saves you valuable time and money.

Versatile TDS Meter: A TDS meter is an indispensable tool for improving your quality of life. This digital water quality tester finds numerous applications in various environments, including drinking water analysis, pool monitoring, pH balancing in RO/DI (reverse osmosis/deionization) systems, aquariums, spas, hot tubs, and hydroponics.

Automatic Temperature Compensation (ATC): Variations in water temperature can affect the accuracy of pH measurements.

This digital pH tester features a built-in thermometer with a measuring range of 0°C to 60°C (32°F to 140°F) and is equipped with automatic temperature compensation (ATC). Three display modes for salinity measurement: The device supports display in three different units: PPM, PPT, and %. For pool salinity monitoring, the measuring range is from 0 to 9999 ppm; for seawater analysis, it is from 10 to 200 ppt (Note: 1 ppt = 1000 ppm; when the ppm value exceeds 9999, the device automatically switches to the ppt display). Finally, for measuring the salinity of food, the range is from 0.01 to 25%. High-precision pH meter: Designed specifically for drinking water analysis, this water quality tester is equipped with a highly sensitive glass probe, capable of taking pH measurements across the entire range of 0 to 14, with a resolution of up to 0.01 pH.
