New Acoustic Calibrators

Cirrus Research plc (UK) announces the introduction of a new range of Acoustic Calibrators. Key features of the new CR:514 and CR:515 are: IEC 60942:2003 Class 2 & Class 1 Performance, 94dB Sound Pressure Level Outpuy, Suitable for use with ½” microphone capsules, Automatic power
switch off with user override giving long battery life, Robust case with ergonomic design.
The CR:514 and CR:515 are high performance acoustic calibrators
designed for the field and laboratory calibration of sound level meters and other noise measurement equipment. The units are simple to operate and meet the requirements of the latest IEC 60942:2003 standard for Acoustic Calibrators with performance to Class 2 (CR:514) and Class 1 (CR:515).
The calibrators provide an output level of 1kHz at a sound pressure level of 94dB and are suitable for use with ½” microphone capsules. Easy access to the battery for replacement as well as a robust
design allow the CR:514 and CR:515 units to be used for both field calibration of sound level meters as well as for precision
calibration of other sound measurement equipment.
A single push button is used to switch on the calibrator and the unit will automatically switch off after 3 minutes to conserve battery life. The user can override the automatic switch off allowing the unit
to be used for longer periods if required.
The calibration of sound level meters and other noise measurement equipment is vital to ensure that any measurements taken are accurate and comply with any regulations and guidelines that are being followed.
The CR:514 and CR:515 Acoustic Calibrators provide a simple and reliable
method of carrying out both field and laboratory calibration of noise
measurement equipment. CR:514 and CR:515 Acoustic Calibrators can be
ordered as individual units and are supplied with a user manual, certificate of calibration and a battery.
