LAQUAtwin pH-22B is a compact type water analysis instrument. Accurate measurement from only a single drop of sample onto HORIBA's original flat sensor. It brings new dimension to your water quality testing.

The only pocket meter that directly measures pH in 0.1 ml sample (or 0.05 ml 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.
