APPLICATION SPECIFIC CALIBRATIONS
Refractometers are used in many industries to measure
concentrations of various substances in solutions.
CONCENTRATION OF DISSOLVED SOLIDS IN COFFEE AND TEA
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 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.
+/- .1% ACCURACY
The SP3000 Programmable Refractometerrepresents the latest technology in refractometers. and includes editing software, for creating, or customizing multi point scales. Reads samples as small as 0.4ml with full scale accuracy of 0.2% using CCD scanner (linear scanned array imaging) technology.
