ensures permanent and undisturbed focus, its highly accurate glass scale is
divided to read angular degrees and also carries sugar scale in ISS units.
The angular scale from 0 to 360 Degrees are sub divided to 1 degree to
enable direct reading to 0.05 degree and by estimation to 0.02 sugar
degrees. The sugar scale from 30 degree to 120 degree. Supplied complete
with polar meter tube, sodium lamp, and transformer instruction manual.
