Cirrus Research is offering the CK:821C sound level meter kit for monitoring noise at work and environmental noise.

Each kit is supplied with a CR:821C sound level meter, a calibrator, windshield, licence-free Deaf Defier3 software and manuals.

A standard two-year warranty is also included that can be extended by 10 years at no additional cost, provided that the instrument is serviced and recalibrated annually by either Cirrus or an authorised service centre.

An optional weatherproof kit is also available, which enables the sound level meter to be used outdoors for up to seven days.

The CR:821C sound level meter is available in Class 1 accuracy and complies with the latest IEC 61672 measurement standard as well as IEC 60651 and IEC 60804.

Data logging of up to 1,300 measurements is possible, and the outdoor measurement kits can be used for unattended environmental noise monitoring with remote access via a GSM modem.

Other features of the CR:821C include data download to a PC via a USB connection and free lifetime updates to the Deaf Defier3 software.

The meter also includes 1:1 octave band filters, which support the selection of hearing protection (PPE).

‘Powerful, robust and easy to use, these sound level meters will help organisations keep within the letter of the law with regard to noise safety and, in the case of workplace noise, help users to select appropriate ear protection,’ said James Tingay of Cirrus Research.
