Overview

The Hanna TDS Tester HI98301 is a handheld digital meter used to measure total dissolved solids in water, giving you a quick, reliable way to check the purity of your RO/DI output or top-up water.

Confirming your RO/DI water is actually producing low-TDS output is essential — a rising TDS reading is often the first sign that your membrane or DI resin needs attention.

Key features

Digital TDS readout for quick, accurate checks
Handheld, portable design suited to regular spot-checking
Hanna build quality, well regarded for reliability

Who it's for

Anyone running an RO/DI system who wants to monitor water purity and catch membrane or resin exhaustion early, regardless of tank size.

Setup & tips

Test your RO/DI output regularly to track TDS trends over time
Rinse the probe with RO/DI water before and after testing to avoid contamination
A rising TDS reading is a good early signal that it's time to replace your membrane or DI resin
