HORIBA LAQUA EC220-K Waterproof Handheld Conductivity, Resistivity, TDS, Salinity & Temperature Meter
Description
HORIBA LAQUA EC220-K Waterproof Handheld Conductivity, Resistivity, TDS, Salinity & Temperature Meter
Product Overview
The HORIBA LAQUA EC220-K is a professional handheld water-quality meter for accurate measurement of conductivity, resistivity, total dissolved solids (TDS), salinity and temperature. Its rugged IP67 waterproof, dustproof and shock-resistant housing makes it well suited to routine laboratory and field testing.
The meter supports automatic and manual calibration, automatic/manual temperature compensation, selectable TDS and salinity curves, and data storage for up to 1,000 readings. A backlit LCD, fold-out stand and protective carry case make operation convenient in a wide range of environments.
