The Fowler Company's product line includes precision tools, electronic measuring instruments, optical measuring instruments, gage calibration equipment, and hardness testers.

With an emphasis on "user-friendly" electronics, they offer primarily industry standard RS232 output for data collection and SPC (Statistical Process Control), not some proprietary signal requiring additional interfaces. They also have a line of non-electronic tools, including high-quality micrometers, vernier and dial calipers, dial and test indicators, rules, gage blocks, stands, magnetic bases, squares, parallels and hundreds of other fine measuring tools essential to industry.
