The digital salt-meter, ES-421 employs a funnel-shaped sensor which measures the salt % of a sample such as the dilute solution of soy sauce, ketchup,mayonnaise, worcester sauce, squeezed juice of pickles, etc. It only needs 1.0ml of sample.
*Improved durability with titanium electrodes.
*Stage is made out of SUS316L.
*Equipped with a backlight for 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).Its concentration has been changed from 2.84%→2.50%.
