Features:
Accurate and Reliable: To achieve high accuracy, it is equipped with a high-quality titanium alloy probe, and reliable automatic temperature compensation (atc) ensures that the readings are always accurate at various temperatures.
Simple and instant: just turn on the ph meter and shake the water gently, then a stable reading will be displayed on the lcd within a few seconds, the tds ppm meter will automatically turn off if there is no operation for more than 5 minutes.
Hold function and auto-off function: Freeze the measurement to view it out of the water. Turn off the meter after 5 minutes of inactivity to save battery.
Widely used: The pocket tds ph meter is the ideal test kit for home and laboratory use. Ideal for testing in water, swimming pools, aquariums, spas, hydroponics, food, wine and brewing.
