The Gralex name has been synonymous with quality digital panel meters for over 30 years. Over this period the company has offered a wide variety of high reliability LED and LCD display products to discerning instrument manufacturers.

Pioneer was founded in 1989 as a product design and manufacturing service. In 1993, the company purchased the Sienko line of keypad test equipment and quickly expanded it to include life test systems, contact bounce instruments and a complete line of tail connectors.

In June of 2002 Gralex and Pioneer merged to form Gralex-Pioneer Corporation. The new firm manufactures and markets a comprehensive line of high visibility digital panel meters and test equipment for membrane keypads and telemetry monitoring. A full range of contract design and manufacturing services are also available.

Gralex-Pioneer products and Services are used today by electronic instrument and equipment manufactures and testing facilities throughout the world.
