HORIBA LAQUAtwin EC-22 Waterproof Pocket Conductivity & Temperature Meter

Product Overview

The HORIBA LAQUAtwin EC-22 is a high-precision pocket meter for direct conductivity and temperature measurement from only 0.12 mL of sample. Its flat integrated sensor lets users place a few drops of sample or standard solution directly onto the measurement surface, removing the need for a beaker.

The EC-22 provides auto-ranging conductivity measurement, three-point calibration, automatic standard recognition, temperature display and temperature calibration. It is an ideal portable option for fast conductivity testing where sample volume is limited.
