About Us

A heritage of precision engineering

Instro can trace our historical roots back to 1964 when it started operations for the UK MoD as a precision engineering contract manufacturer. Today, that heritage of precision engineering and rugged design is at the core of our products which are fielded in more than 50 countries.
