Cirrus Research plc, the UK company which specialises in the design and development of noise measurement equipment, has upgraded its high performance CR:800C series of sound level meters, to include a wide range of new features and functions. Suitable for both occupational and environmental noise measurement, the new CR:800C sound level meters are also supplied with Cirrus’ new ‘2-12’ year guarantee. This enables Cirrus’ standard two year warranty to be extended by ten years, at no additional cost, provided that the instrument is serviced and recalibrated annually by either Cirrus Research plc or by an authorised service centre.

Like their predecessors, CR:800C sound level meters are easy to use, yet capable of meeting sophisticated modern noise measurement guidelines. They are available in Class 1 or Class 2 accuracy and now comply with the latest IEC 61672 measurement standard as well as IEC 60651 and IEC 60804. Data logging of up to 1300 measurements is now possible, and outdoor measurement kits are available for unattended environmental noise monitoring with remote access via an optional outdoor measurement kit and GSM modem.
