Martinez Measurements was established in 2002 by its President, William G. Martinez. For most of its term the business has operated as a sole proprietorship, offering custom strain gage and instrumentation services to the aerospace industry. Functioning primarily as a sole source supplier to industries small and large, the business has grown significantly through direct industry contacts and associations. The attributes of the business are its expertise and unique skills in applying custom strain gage transducers to complex components and structures in a timely, cost effective manner. Experience, ingenuity, versatility, low overhead and rapid turn time are the hallmarks of the business. As a result of our rate of expansion, Martinez Measurements has recently taken on partnership, with the intention of expanding its services to a broader customer base.
