Your lab-in-a-pocket 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.
The only pocket meter that directly measures the calcium ion concentration in a 0.3 mL sample (or 0.05 mL with sample sheet B). Its unique sensor allows measurement of viscous liquids, solids, and even powdered samples. You do not need a beaker to calibrate the meter or measure a sample. Simply place a few drops of the standard or sample on the flat sensor. This procedure saves you time and prevents you from wasting your valuable sample.
