Designed to measure varying concentrations of dissolved metals, minerals, and salts within liquids, they can help determine whether or not a water source is fit for general use and consumption.

Editor's Notes

November 27, 2018:

Added the Soeks EcoVisor F4 for its multifunctional design and easy-to-use touchscreen interface. The HM Digital DM-1 was one of the few inline options I found that can measure both input solution and output liquids for filtration/purification systems. Also included the Bluelab Guaradian for its dedicated hydroponics applications. The backlit LCD on the HoneForest Tester is capable of flashing both red and green, making alerts easy to tell apart from one another. Finally, added the Thomas Traceable for its chemical-resistant design and large, easy-to-read digits.
