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 digital salt-meter, ES-421 employs a funnel-shaped sensor section (conductivity), which measures the salt % of a sample, such as dilute solution of soy sauce, ketchup,mayonnaise, Worcester sauce, sqeezed juice of pickles, etc.
Only very small sample needed, where approximately 1.0mL is enough for measurement.
The NaCl solution for calibration is different from the solution used for the former ES-421 (Cat.No. 4210). The concentration of the NaCl solution for calibration has been changed from 2.84%→2.50%.

4211 Salt Meter ES-421 | Application Examples
A potato chips manufacturer
Salt is sprinkled on fried potato slices from a machine, and the amount of salt dispensed is checked and adjusted at the beginning of a production lot. In the past, we had to take samples to the lab for testing, but now we can do it right at the production line.
The ES-421 saves us time and money because it does not use reagents like titration systems. Even the disposal of the titrating reagents is not free. ATAGO’s salt meter is environmentally friendly and economical.
A condiment manufacturer
We are testing sauces and dressings for salt with the
ES-421.The instrument is perfect for use at the production site because it is compact and does not use harmful chemicals.
A canned food manufacturing plant
We are using the PAL-SALT to measure the brine for canned tuna. It is easy to use and completely washable under the faucet. We liked it so much that we purchased a second unit.
