TDS-2B Digital LCD Water Quality Tester Meter Professional Measuring Pen for Water Hardness and Mineral Impurity Content

Unique Temperature Compensation Function: Can automatically convert the TDS value to a water temperature of 25℃

TDS Value: Represents the total content of soluble substances in water, e.g., calcium, magnesium ions, and certain trace elements, etc.

Large LCD screen, waterproof design, easy to view TDS value (cannot test pH or the specific value of a substance dissolved in the solution)

More Accurate and Faster: Titanium alloy test probe; the measurement value is not affected by the magnetic field in the water, resulting in a more accurate measurement.

Energy Saving and Durable: Long operating time without frequent battery replacement; normal use lasts for two years (1.5V*2 button batteries)
