Horiba LAQUAtwin Pocket Meters

Your lab-in-a-pocket. Available for pH, Conductivity, Salt, Sodium-Ion, Potassium-Ion, Nitrate-Ion or Calcium-Ion.

HORIBA's unique compact meter integrates the electrode, display and sample container to enable simple, effective on-site testing by direct measurement from a single drop.

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.
