Pulsar - Model 105 (Class 1) and 106 (Class 2) - Acoustic Calibrator - Brochure

Acoustic Calibrator Models 105 (Class 1) and Model 106 (Class 2) have been tested and formally EU Pattern Approved by the PTB (under certificate PTB-1.61.4034842), as meeting all of the requirements of the latest International standard, IEC 60942: 2003 (equivalent to ANSI/ASA S1.40-2006). This version of the IEC international 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 field calibrate (that is set the sensitivity), of any properly approved noise meter that uses a standard measurement microphone.
