HORIBA LAQUAtwin EC-11 Waterproof Pocket Conductivity Meter

Product Overview

The HORIBA LAQUAtwin EC-11 is a compact pocket conductivity meter designed for fast on-site testing from a single drop of sample. Its integrated flat sensor, display and sample well allow direct measurement without a beaker, helping reduce sample use and simplify routine conductivity checks.

The EC-11 uses a two-electrode bipolar AC measurement system with a titanium sensor coated in platinum black. It offers automatic range selection, automatic calibration, automatic recognition of conductivity standards and fixed automatic temperature compensation.
