Nor1525

De Nor1525 is een volledig set voor opbouw van een eigen kalibratie labo.
Met de Nor1525 kan men een akoestische en elektrische kalibratie doen van geluidmeters, microfoons, voorversterkers en kalibrators.

Periodic Verification of Sound Calibrators

• Sound pressure level corrected for pressure, temperature and humidity
• Short term stability expressed in dB (option)
• Output frequency in Hz
• Total distortion in % (option)

Periodic Verification of Sound Level Meters
The Periodic Verification of Sound Level Meters can be performed in accordance with several national and international standards. This includes measurements of:

• Accuracy of input range selector
• Level linearity
• Spectral weighting networks A, B, C, Z, Lin and Flat
• F, S, and I time constants. Pulse measurement capability
• RMS detector capability
• Overload detector
• Inherent noise using microphone equivalent or acousti-cally insulated test vessel
• Integrating averaging functions Leq and SEL
• Noise dose
• 1/1 and 1/3 octave band filters (option)

Features

• Frequency response calibration of microphones using the electrostatic actuator (with swept-sine) or acoustical method
• Sensitivity calibration of microphones using the insert voltage method ensures a high degree of accuracy
• Fast and accurate calibration of sound calibrators, pistonphones and associated barometers in accordance with IEC 60942 (2003 and 2017)
