4-in-1 pH/TDS/EC/Temperature Meter 0-19990ppm — Digital Water Quality Tester for Pools, Aquariums & Drinking Water

Compact 4-in-1 tester that measures pH, TDS (0-19990ppm), EC and temperature for quick on-the-spot water analysis. Built with a high-quality alloy probe and reliable automatic temperature compensation (ATC), it delivers consistent, accurate readings across varying temperatures. To use, switch the meter on and gently agitate the sample — a stable value will appear on the LCD within seconds. A Hold function lets you freeze the displayed measurement so you can view it after removing the probe from the water. The unit also conserves power with an automatic shut-off: the meter turns off after 5 minutes of inactivity. Pocket-sized and easy to operate, this meter is suitable for home or laboratory use and ideal for testing pools, drinking water, aquariums, spas, hydroponics, food, wine and brewing.
