Product Options


Eutechs TDS 6+ is a sturdy and economical water tester ideal for basic water testing needs, accuracy is delivered to ±1% full scale accuracy with multi point push-button calibration options of automatic or manual. If you require quick, easy calibration then the automatic mode with preset calibration points at most popular values is the simplest option or manual calibration can be chosen for more flexibility.

This tester comes complete with many simple but effective features to ensure accurate results are given such as auto-ranging for conductivity/TDS measurements for fast response and best resolution over wide measurement ranges, built in ATC in the electrode is designed to provide optimum accuracy under fluctuating temperatures and a handy hold function momentarily freezes readings for easy viewing. Auto-power off saves battery power after non-use and self diagnostic message codes make troubleshooting easy.

An optional meter kit contains everything needed for calibration and measurement in a rugged carrying case.

TDS is only relevant in freshwater systems as salinity will dramatically increase the conductivity and therefore apparent TDS.
TSS are particles that are larger than 2 microns found in the water column. Anything smaller than this is called a dissolved solid.
