pH/TDS Meters

Hydroponic growing requires precise monitoring of pH and Total Dissolved Solids (TDS).

We offer a variety of pH and TDS meters from leading brands like HM Digital Instruments. These quality meters are designed for both home and commercial use, and come in a variety of styles.

If you want one-time disposable strips, our most popular pH/TDS option are the Rapitest Soil Test Kit from Luster Leaf.
