Features

The only pocket meter that directly measures sodium ion concentration in 0.3ml sample (or 0.05ml sample with sampling sheet B) and converts it into salinity or NaCl salt concentration. No need for a beaker to calibrate the meter or measure a sample. Just place few drops of the standard or sample onto the sensor. This procedure saves you time and prevents wasting your precious sample. 

  • Minimum sample volume: 0.3ml (0.05ml with sampling sheet B)
