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
