3700 Series

3700 Series Brochure

The 3700 Series model is our top of the line 14" horizontal beam optical comparator. The 3700 is the ultimate system for load capacity and accuracy. It features an erect image and S-T's exclusive gothic arch bearing ways which provide the best accuracy and life.

*NOTE: "3788" Series CNC 14" Optical Comparator. The "3788" has all of the fine features of the standard "3700" 14" comparator PLUS the benefit of high-speed stepper motor drives and CNC positioning. Simple, yet powerful part programming and optical edge sensing converts the optical comparator into a fully automated inspection system.

Digital Readouts
