ATAGO POCKET BARISTA
The PAL-COFFEE is capable of measurements at a high resolution (RES).
The 0.01% resolution allows for precise management of even the slightest variations in tea or coffee concentration. The unit is capable of automatically detecting temperature stability, which allows for stable, consistent measurements even at high temperatures—such as when measuring hot, freshly brewed coffee.

APPLICATION SPECIFIC CALIBRATIONS
Refractometers are used in many industries to measure concentrations of various substances.
Examples are:
CONCENTRATION OF DISSOLVED SOLIDS IN COFFEE
CONCENTRATION OF PROPYLENE GLYCOL IN COOLANT
CONCENTRATION OF ACID IN BEER AND WINE
CONCENTRATION OF FRUCTOSE AND WATER IN HONEY
PLOTTING A CORRELATION SCALE
(WORKS ON ALL MODELS)
Just like any other indirect method correlation, a number of raw data readings from samples with different concentrations of a substance need to be collected (BRIX Values), along with the corresponding direct method data with concentration measurements.
For tea and coffee, the 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.
The brix measurements from the refractometer, and the corresponding TDS Measurements from the moisture balance, are then plotted on an Excel Spreadsheet
Using the chart function in Excel, a formula may be obtained from the data points, and applied to
any other values going forward. The more data points, the more robust the formula will be.
