​APPLICATION SPECIFIC CALIBRATIONS
Refractometers are used in many industries to measure 
concentrations of various substances in solutions.
Examples are:         

PLOTTING A CORRELATION SCALE
(WORKS ON  ALL REFRACTOMETERS)

Just like any other indirect method correlation, a number raw data values (refractive index) from samples with different concentrations of a substance need to be collected, along with the corresponding direct method data with concentration measurements.

For tea and coffee, the direct measurement of total dissolved solids (TDS) is obtained easily with the use of a moisture balance 

The moisture balance is used to evaporate the moisture from a sample, and weigh it simultaneously in real time. The rate of drying
​is constant, until all surface moisture has evaporated. 

The moisture balance senses the change in the rate of drying, and automatically shuts off, giving a percentage of moisture reading, the inverse of which is the amount of remaining solids.
ONLY THREE DROPS REQUIRED.
