Conductivity (EC) Meters

Conductivity (EC) Meters
Conductivity meters are preferred over TDS by commercial growers, why? Because they give the best estimate of actual strength of a  given nutrient solution.
Information Centre
TDS is a estimate while Conductivity is exact. The total TDS is a bulk estimate and  dependent on the mixture of nutrients and the concentration while Conductivity  is only dependent on the concentration of nutrients.

Conductivity meters are sometimes called EC test meters. They measure the conductivity of water, this is a measurement of electrical conductivity/ ion levels in the water. There are many manufacturers of EC meters, but our main suppliers are HM Digital who offer a complete range of water testing meters. They offer electrode replacement, at sensible prices too.
