The MISCO Palm Abbe has a high-precision thermistor that is in contact with the fluid. This thermistor is able to accurately sense the exact temperature of the test sample. The internal microprocessor interprets the signal from the thermistor and applies a correction to the readings based on the temperature difference and percent volume for the fluid under test.
The most amazing feature is that the digital refractometer can utilize multiple temperature correction tables for different fluids over a wide temperature range. A digital refractometer can also be custom programed to measure your specific fluids and can have custom temperature compensation tables as well.
