HM Digital AP-1: AquaPro Water Quality Tester (TDS Meter)


How pure is YOUR water?

Nothing is more important than water. As a crucial part of our existence, we need to be certain that the water we consume and provide for our families is of high quality. Tap, well and even filtered water quality is prone to fluctuation and possible contamination. Testing regularly enables you to be sure of your water's purity.


The Aquapro digital water tester is your first step to high quality water. With the push of a button, the AquaPro measures TDS, an indicator of general overall water quality. The lower the TDS level, the purer your water.


HM Digital's AquaPro series of handheld TDS/EC meters come in a sleek design that's perfect for the modern kitchen. These digital water testers are the next generation for today's tech-savvy and health-conscious consumer.


This small compatible TDS / TEMP Meter is MAGNETIC which allows you to attach it to your fridge or other convenient place. A must-have tool for all health conscious families.
