TDS Meter 3-in-1 Digital Water Quality Tester | Bowlift Floor 1x Ultra Loud Survival EmergencyYou don't know if your tap water is really clean and you still don't test it. Every day you drink water without knowing what is dissolved in it. A TDS meter shows you in seconds the exact content of dissolved solids, the electrical conductivity, and the temperature of your water whether from the tap, filter, aquarium, or pool. Simply hold the device in the water, and you'll see immediately if your filter is still functioning or needs to be replaced.
