This instrument can be used measuring oils, fats and waxes giving a reading directly in terms of the oil scale, otherwise known as BUTYRO Scale. The micrometer eyepiece allows an accuracy on their scale of 0.1 the soil scale may also be conversion tablets. This allows for measuring materials with an index of refraction in the range 1.42 to 1.49 to an accuracy of 0.0002. Dual scale: Sugar percentage scale & Butyro Scale. Subdivided at a 1% interval. Easy temperature control. No coloration of the filed view.
Micrometer allows an accuracy of 0.01% on the oil (Butyro) scale.
