The Acoustic Calibrator
Class 1 and Class 2 Calibrators with Pattern Approvals
Our acoustic calibrator (sound calibrator) is suitable for the field and laboratory calibration of sound level meters, noise dosimeters, and other noise measurement instruments.
The unit is simple to operate and meets the requirements of the latest IEC 60942:2017 standard for acoustic calibrators with performance to Class 1 or Class 2.
Pattern Approval
The CR515 Class 1 Calibrator has PTB, LNE and CEM Pattern Approval.
The CR514 Class 2 Calibrator has PTB Pattern Approval.
Pattern Approval is a method where a test laboratory such as the Centro Español de Metrología (CEM) tests an instrument against a set of standard tests to ensure that it meets the performance claims of the manufacturer. Find out more here.
