Butyro Refractometer

ALPHA CHEM- 1034 Butyro Refractometer

This instrument can be used for measurement of fats in ghee and other such products giving a reading directly in terms of the oil scale also known as butyro scale, the micrometer eye-piece allows an accuracy on this scale of 0.1 and the oil scale may also be converted into a retrative index scale using conversion tables. This allows measurements on materials with index of refraction in the range of 1.42 to 1.49 with an accuracy of 0.0002 as tables are supplied for converting oil scale reading into index of refraction, relative to mean sodium lines. The pism box is water jacketed for temperature control and a sample achromatising device enable the removal for all colours from the border line thus enabling the instrument to be used what white light.

The instrument is provided with a test liquid for checking and resetting the scale if necessary and is encased in apratable wooden box. Refraction range from 1.42 to 1.49 with accuracy of 0.0002 fitted width sugar and oil scale sugar scale 50-80% and oil scale 0-100%.
