They do not identify specific contaminants, minerals, or chemicals in water. A low TDS reading does not confirm that water is free of all contaminants. For specific water quality concerns, contact your local utility or a certified water testing laboratory.\u003c\/p\u003e\u003ch3\u003eReplacement schedule:\u003c\/h3\u003e\u003cp\u003eBatteries are replaceable.
