Accurate measurement from only a single drop of sample onto HORIBA's original flat sensor. LAQUAtwin product line-up offers easy, quick, and reliable measurement of 8 parameters. It brings new dimension to your water quality testing.

LAQUAtwin pH-11

Overview

pH 
Water proof Micro Volume  0.1 pH 2-point calibration 

Features

The only pocket meter that directly measures pH in 0.1ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample.
