Introducing the sole compact meter designed for swift measurement of potassium ions utilizing ion-selective membrane technology. Leveraging flat sensor technology refined over 60 years of sensor engineering, it ensures dependable and direct measurements from just a drop of sample, starting from 0.3 mL. Employ a sampling sheet (available separately) to extend measurements down to 0.05 mL or more. Its unique sensor mechanism enables direct measurements of solid, viscous, and powder samples, eliminating the need for a beaker during calibration or measurement. Simply drop the standards and sample onto the flat sensor, saving time and minimizing sample wastage. This lightweight, pocket-sized meter is versatile for use in research and industrial applications across diverse fields.

Key Applications:

  • Soil and sap testing 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.)

Remember, this compact meter for potassium ions is specifically tailored for measuring ions in water and is not be suitable for measuring electrolytes in oils.

Also known as:
Potassium meter, compact potassium meter, pocket potassium meter, potassium ion meter, potassium ISE meter, HORIBA potassium meter, Laquatwin potassium meter, potassium in plant sap
