A method of measuring of vertical refraction by observed representation of reading scale, which is on the mirror reflector, has been suggested. This method permits direct determination and inserting correction as refraction as result of geometrical leveling.

The new way of measuring of vertical refraction with application of refraction devices is considered in the article. It helps to simplify methods and means of immediate determinations of vertical refraction and to raise the accuracy its measuring.
