Aspen Instek Specialising in the design and manufacture of test and measurement products

Specialists in the manufacture of measurement and testing equipment

GW Instek was established in 1975, specialising in the design and manufacture of a wide range of test and measurement products. Initially GW Instek concentrated on producing power supplies and then oscilloscopes. Over time the range was expanded to include most basic test and measurement equipment.

Today, GW Instek has seven key instrument product lines which are ideally suited to R&D, product development, manufacture and service applications. With regional offices and manufacturing in Taiwan, California, China and Malaysia, GW Instek products offer impressive performance, excellent quality and exceptional value for money.

In April 2003 GW Instek appointed Aspen to support the UK market as part of their worldwide distribution network. Aspen is delighted to offer the complete Instek range, with many models being available directly from UK stock.

Aspen themselves began trading in 1974 and currently distributes a wide range of RF & Microwave Components and Test Equipment.

Aspen maintains a particularly well equipped service and repair laboratory, which specialises in supporting many of the products supplied.
