HM EC Pen and TDS Nutrient Meter With Temperature

The HM EC/TDS Hydrotester Pen provides a digital readout of the EC (Electrical Conductivity) and TDS (Total Dissolved Solids) in a nutrient solution. The EC refers to a substances ability to conduct electricity, whereas TDS is the combined total of any minerals, salts or metals dissolved in water or other liquids.

At Aqua Gardening, HM EC meters have proven themselves tough, waterproof and able to withstand drops. We've used the same EC pen for more than 3 years without an issue. The HM EC pens calibrate quickly, and automtically, with the EC 2.76 solution.
