Using a conductivity method of testing, the ATAGO Digital Salt-Meter is used for measuring the level of salinity in a solution of soluble materials.
The digital salt-meter, ES-421 employs a funnel-shaped sensor section ( conductivity ), which measures the salt % of a sample ( dilute solution of soy sauce, ketchup,mayonnaise, Worcester sauce, sqeezed juice of pickles, etc. ) very small sample needed ( 1.0ml approx. is enough for measurement ).
