Introducing the only compact meter designed to measure sodium ion concentration and calculate it into salinity or NaCl salt concentration, unlike conductivity-converted meters. Leveraging flat sensor technology and 60 years of sensor engineering, it ensures a reliable and direct measurement of a drop of the sample from just 0.3mL. With its unique sensor mechanism, it enables direct measurements of solid, viscous, and powder samples, while the use of a sampling sheet (available separately) extends measurements down to 0.05mL.

No beaker is needed for calibration or measurement. Simply drop the standards and sample onto the flat sensor, saving time and minimizing sample wastage.


  • Soil and sap testing for improved agriculture
  • Food testing* (Note: Only detects ions in water; cannot measure electrolytes in oils. Ion measurement may be affected by non-target ions.)

Key Functions:

  • Autocalibration function recognizes standards and offers user-selectable options for one- or two-point calibrations.
  • Auto range change feature
  • Temperature compensation
  • IP67 waterproof rating for durability
  • Auto hold function
  • Automatic power off after 30 minutes

This compact meter provides efficient and accurate measurements for a variety of applications in agriculture and food testing.
