15 year warranty

This cover starts with a two year 'return to base' warranty against all faults but it is then extendable, one year at a time up to a maximum of 15 years, as long as the products are calibrated annually by Cirrus Research.

This guarantee covers all noise measurement and acoustic equipment and is available at no additional upfront cost.

"It doesn't matter if the damage has been caused accidentally or by some kind of failure, we will mend or replace it," marketing manager, Thomas Shelton said. "We know the reliability and the strength of Cirrus products and that's why we can offer such a long term warranty to cover any eventuality as part of our follow-on Customer Service."
