Each kit is supplied with a CR:812C Sound level meter, a calibrator, windshield, licence-free Deaf Defier3 software and manuals. 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 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.
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), using Cirrus' Deaf Defier3 software which is supplied as standard.
"Our CK: 821C sound level meter kits are an ideal choice for professional noise measurement applications, from Noise at Work risk assessment to environmental noise measurements", said James Tingay of Cirrus Research. "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."
