Kaelus is a recognized leader in Test and Measurement Solutions, PIM Test analyzers, cell-site filters, combiners and tower mounted amplifiers. Kaelus is a business within the Smiths Interconnect division of Smiths Group. Kaelus was formed by the consolidation of four previously independent Smiths brands including:

Summitek Instruments: The industry expert in PIM Test equipment.
Triasx: A leader in Portable PIM Test equipment and network enhancing site solution products.
Allrizon: A global supplier of front end radio BTS and radio link products.
Telecom Division of TRAK Microwave: A global supplier of ferrite and circulator products.

In November 2010 Smiths reorganized these four existing businesses to strategically align them within a single management structure under a new trading name, Kaelus. This bold move to create a single technology-rich brand, combining the substantial heritage and industry awareness of the legacy businesses, provides technically differentiated offerings and allows a more effective use of global resources and reach, maximizing the benefits delivered to customers.
