Four meters in one.
These meters test pH, conductivity (EC), Total Dissolved Solids (TDS) and temperature with a single probe. They are easy to use with all selections controlled by only two buttons. Waterproof, the meters may be used in any weather. New technology using gel electrolyte and a cloth junction for the pH sensor, and graphite for the EC/TDS sensor eliminates oxidation and polarization errors. The meters come with probe and a hard carrying case.
Available in two models (low range and high range), with auto-calibration and auto-temperature compensation. 500 hrs. of use from 4 1.5V batteries (included).
