Hemisphere kits

Hemisphere kits

The G.R.A.S. hemispheres are compliant with the ISO 3744, 3745 and 3746 (ANSI S12.54, S12.55, S12.56) standards and accommodate for 4, 10 and 20 positions. These are clearly marked to ease the mounting and maintain measurement repeatability. Two hemisphere structures are available; a 1 m measurement radius and a 2 m measurement radius.
