Only compact meter for a quick measurement of calcium ion using ion-selective membrane. Flat sensor technology and 60 years of sensor engineering realizes a reliable and direct measurement of a drop of the sample from 0.3mL. Use sampling sheet (sold separately) to measure down to 0.05mL or more. Unique sensor mechanism realizes the direct measurement of solid, viscous, powder samples. No need for a beaker to calibrate or measure. Just drop the standards and sample on the flat sensor, saves you time and minimize wasting your precious sample. This lightweight, pocket-sized meter is suitable for research and industrial applications in diverse fields.
Soil and sap testing (measures free calcium in plant sap) for improved agriculture; food testing*
Calcium in milk.
* Detection of ions in water only; electrolytes in oils cannot be measured. Ion measurement can be affected by non-target ions.
