ORP Meter
The LAQUAtwin ORP-11 Compact Water Quality ORP Meter is unique compact meter integrates the electrode, display and sample container to enable simple, effective on-site testing by direct measurement from a single drop.ORP’s are measured by using a meter with a mV function, in combination with a noble metal electrode (gold or platinum) and a reference electrode. ORP’s ARE affected by temperature, so must be measured at a constant temperature.

Conductivity Meters
Our LAQUAtwin EC meter provides an efficient, quick, and easy method that accurately measures the electrical conductivity (EC) of a liquid, allowing you to determine the nutrient concentration of your samples quickly and easily, such as the conductivity of soluble salts on plant growth. Conductivity (or EC) is the measure of total dissolved salts in a solution, the factor that influences a plant’s ability to absorb water. In horticultural applications, monitoring of salinity helps manage the effects of soluble salts on plant growth. EC is a meaningful indicator of water quality, soil salinity and fertilizer concentration.
