Potassium ion meter LAQUAtwin K-11

portable

Overview
HORIBA's compact portable potassium meter integrates electrode, display and sample holder for direct measurement from a single drop or by immersion. The LAQUAtwin K-11 is configured for accurate, rapid potassium testing in whole blood, plasma, milk and abomasal fluid, supporting routine monitoring in veterinary and medical environments.
