Model 105 & 106

Acoustic Calibrator

 

Acoustic Calibrators from Pulsar are EU Pattern Approved and meet IEC 60942:2003 Models 105 and Model 106 are new a technology acoustic calibrator that has been tested and formally EU Pattern Approved under certificate PTB-1.61.4028829, as meeting all the requirements of the latest International standard, IEC 60942: 2003.

This version of the IEC standard is far more stringent than previous versions and so far very few manufacturers have managed to meet it.

The two models are intended to calibrate, that is set the sensitivity, each Pulsar acoustic calibrator or any properly approved sound level meter that uses a standard measurement microphone.

Both Models 105 and Model 106 give a standardised 1kHz tone - the frequency where all weighting networks are the same, at a pressure of 1 Pascal which is a sound level of 94 decibel. They have sensors to correct for temperature, humidity, barometric pressure and battery voltage so that they remain stable and accurate under almost any conditions where they are likely to be used.

Model 105 complies fully with Class 1 - the precision class, while Model 106 fully meets the requirements for the calibration of industrial sound level meters used in almost all Health and Safety applications. As today, almost all approved sound level meters use the Internationally standardised “1/2 inch” microphone, the microphone cavity is this diameter, but adapters are available for smaller microphones such as 1/4 inch.
