The only compact meter capable of swiftly measuring calcium ions employs ion-selective membrane technology. With flat sensor technology honed over 60 years of sensor engineering, it enables reliable and direct measurements from just a drop of sample, as little as 0.3 mL. By utilizing a sampling sheet (available separately), measurements can be extended to as low as 0.05 mL or more. Its unique sensor mechanism facilitates direct measurements of solid, viscous, and powder samples, eliminating the need for a beaker for calibration or measurement. Simply drop the standards and sample onto the flat sensor, saving time and minimizing sample wastage. This lightweight, pocket-sized meter finds utility in research and industrial applications across diverse fields.
Key Applications:
- Soil and sap testing (measuring free calcium in plant sap) for enhanced agriculture
- Food testing (Note: Only detects ions in water; cannot measure electrolytes in oils. Ion measurement may be affected by non-target ions.)
- Calcium measurement in milk
Key Functions:
- Autocalibration function capable of recognizing standards, with user-selectable options for one- or two-point calibrations
- Automatic range change feature
- Temperature compensation functionality
- IP67 waterproof rating for durability and reliability
- Auto hold function for ease of use
- Automatic power-off after 30 minutes to conserve battery life
