• Digital Salinometer

Digital Salinometer

  • Measurement Range: 0.00 to 10.0%
  • Ambient Temperature: 10 to 40°C
  • Automatic Temperature Compensation

The digital salt-meter, ES-421 employs a funnel-shaped sensor section (conductivity), which measures the salt % of a very small sample (1.0ml approx. is enough for measurement).

  • Improved durability with titanium electrodes and a sample stage made out of SUS316L.
  • Equipped with a backlight to produce an even brighter, easier to read display.
  • Equipped with an “Offset Function.”
  • The NaCl solution for calibration is different from the solution used for the former ES-421(Cat.No4210).
  • The concentration of the NaCl solution for calibration has been changed from 2.84%→2.50%.


  • dilute solution of soy sauce
  • ketchup
  • mayonnaise
  • Worcester sauce
  • sqeezed juice of pickles
  • etc.
