We supply ultra-strong surface plates that verify flatness and serve as accurate reference planes for gages. The plates provide a completely flat base for taking height gage or dial indicator measurements. Our products feature tough materials that offer multiple advantages, from less maintenance to minimal thermal expansion. We also have durable plate covers to provide exterior protection. With a surface plate, you can determine if another surface is truly flat, or if it has curves, bowing or rounding. Instruments stands and base comparators also serve as accurate references for professional inspections.
