OkaeYa Digital LCD TDS Meter Waterfilter Tester for Measuring TDS3/TEMP/PPM,Multicolor

This is a digital TDS meter tester used for measuring Total Dissolved Solids present in the water. To measure the purity of water, please use the following instructions. Operating Instructions: Taking TDS Measurements Remove the protective cap. Turn the TDS meter on. The ON/OFF switch is located on the panel. Immerse the meter into the water/solution up to the maximum immersion level (2 inch). Lightly stir the meter to dislodge any air bubbles. Wait until the display stabilizes.

After usage, shake off any excess water from your meter. Replace the cap. Taking Temperature Measurements Once the meter is on, the temperature function can be used at any time, in or out of liquid. Press the TEMP button. The display will switch to temperature (in Celsius only). To return to TDS mode, press the TEMP button.
