What it does for your water
The Droplytix DW-R20-S10 Digital Water Tester is a digital tester that tests for pH, hardness, chlorine, nitrate, nitrite, fluoride, iron, lead, heavy metals, alkalinity and additiona.
Check what a digital tester measures: a TDS meter reads total dissolved solids, which is not the same as hardness.
Softeners are sized in grains per gallon; divide a mg/L or ppm reading by 17.1. The hardness converter does it for you.
Other listed details: model DW-R20-S10; material Reagents.
