A2S Water Filter TDS Tester

Accurate and Reliable Measurements

This digital water tester is equipped with a high-precision chip and a high-quality titanium alloy probe, ensuring the accuracy and stability of water quality testing, making it a reliable tool for water quality testing.

Upgraded 4-in-1 Functionality and Auto Shut-Off

This digital TDS tester features a 4-in-1 design, allowing a single water quality testing pen to measure TDS (Total Dissolved Solids), EC (Electrical Conductivity) and temperature (°C/°F). After completing a measurement, the TDS tester will automatically shut off within five minutes if no further operations are performed, saving power and enhancing convenience.

Large Backlit Screen

This digital water tester features a large backlit display screen, allowing for easy reading even in low-light or dark environments. When the measurement value exceeds 40 ppm, the screen will display a red alert. When the measurement value is below 40 ppm, the screen will display green.

Easy to Use

First, remove the protective cover, then press the power button to turn on the meter. Immerse the digital water tester in water, ensuring the depth does not exceed 1.6 inches. Finally, wait for the display to stabilize. The TDS tester automatically compensates for temperature changes. Once the reading stabilizes (10–30 seconds), press the “Hold” button to remove the TDS tester from the water and view the reading.

Wide Application

This digital TDS tester can not only test the purity of drinking water to ensure that the TDS value is within the normal range, but also test daily water use, hydroponic plants (testing nutrient solutions), swimming pools, and hot springs. You can also use it to test whether water filtration systems (such as reverse osmosis (RO)/DI systems, microfiltration machines) are functioning normally and whether the filter cartridges need to be replaced.
