Stands
SERIES 215 — Granite Base Comparator Stands
• The plates are made of natural stone and will hardly deteriorate over time. • The rigid granite base is free from burrs and pileups due to its fine-grain composition and less viscousness compared with casting iron. The flatness is always accurate.

Note 1: Perpendicularity of the stem hole to the anvil is better than 0.2 mm/100 mm. Note 2: Take note that when mounting high-accuracy Linear Gages (with resolution of 0.1 μm or better) to these stands, accuracy may be affected depending on the perpendicularity of the mounting hole to the top surface of the anvil (cosine effect). Note 3: Compact dial indicators (bezel ø31, ø36) are not suitable for use with these stands.
