The Horiba LAQUAtwin K-11 potassium ion meter performs accurate measurements of potassium ion concentration from only 0.3mL of sample, or 0.05mL sample with sampling sheet B. By requiring only a few drops of the standard or sample the LAQUAtwin K-11 potassium ion meter saves time and prevents sample waste by eliminating the need for a beaker to calibrate. It's unique sensor can measure viscous liquids, solids, and powder samples. This meter is ideal for submersible and small sample or solid sample applications.
