  To produce a radio isotope for Positron Emission To-mography (PET), 10 MeV compact Cyclotron was in-stalled at Sungkyunkwan University. This cyclotron had been produced 10 MeV proton beam. For this cyclotron magnet, the magnetic field measurement instrumentation was being developed. The hall probe sensor was used for field measurement. This hall probe sensor moves radial direction and angular direction by mechanically. The Magnetic field measurement instrumentation measures the field in the range of 5 mm for radial direction and 1 degree for angular direction. Magnetic field was measured with and without cooling. Magnetic field was carried with 4 Gauss without cooling and 0.1 Gauss with cooling. Our developed magnetic field measurement instrumentation has 0.1 Gauss of an error and 0.01 Gauss of resolution over 9 hours.
