HORIBA LAQUA twin pH-11 Waterproof Pocket pH & mV Meter

Product Overview

The HORIBA LAQUA twin pH-11 is a compact pocket meter for convenient pH and millivolt measurement of small liquid samples. Its flat glass electrode sensor allows testing with as little as 0.1 mL of sample, making it suitable for drops, small containers and routine spot checks.

The meter features automatic buffer recognition, automatic temperature compensation, auto-stable/auto-hold measurement and an IP67 waterproof and dustproof construction. The replaceable sensor and included carrying case support practical day-to-day testing in the lab, field and workplace.
