What is a Salt Meter?

A salt meter is an instrument that is used to measure the amount of salt present in a substance.

ATAGO uses both the electrical conductivity method and the refractometer method for our salt meters

• The electrical conductivity method uses salt (NaCl) to conduct more electricity than other substances to ascertain the salt concentration by measuring the electrical conductivity.
• The refractometer method uses the fact that refractive index increases as salt concentration in an aqueous solution increases.
