Application Examples

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.

Why measure salt content?

Adding salt is one of the most critical processes in food manufacturing as it has a significant effect on the color, taste, and texture of food.

ATAGO salt meters are ideal for quick and easy salinity checks on the production floor.

Recently, in addition to use in the production are, many companies are validating our salt meters as the preferred method in lab setting as well. Food scientists are choosing to limit the use of precipitation titration with harmful sliver nitrate (Mohr's method).

Because ATAGO salt meters are sage, fast, and simple.

Due to the difference in measurement principles, reading from the conductivity salt meters may not match up exactly with the reading by titration for certain samples. However, by creating a conversion table between the two testing methods, correlation between the set of results can be seen.

Unlike titration, no expensive and harmful chemical is involved in the measurement process.

ATAGO delivers the revolutionary salinity measurement solution that is both eco-friendly and cost-effective.
