The 4231 is a calibrator from Bruel & Kjaer. Electronic calibrations are necessary for maintaining your equipment for general monitoring and testing purposes. Calibrators enable you to solve problems with your equipment on your own, on site.
Additional Features:
Calibration of sound level meters and other sound measurement equipment
Conforms to EN/IEC 60942 (2003) Class LS and Class 1, and ANSI S1.40 – 1984
Robust, pocket-sized design with highly stable level and frequency
Calibration accuracy ± 0.2 dB
94 dB SPL, or 114 dB SPL for calibration in noisy environments
Extremely small influence of static pressure and temperature
Sound pressure independent of microphone equivalent volume
1 kHz calibration frequency for correct calibration level independent of weighting networks
Fits Brüel & Kjær 1" and 1/2" microphones (1/4" and 1/8" microphones with adapter)
Switches off automatically when removed from the microphone
A handy, portable sound source for calibration of sound level meters and other sound measurement equipment. The calibrator is very robust and stable, and conforms to EN/IEC 60942 Class LS and Class 1, and ANSI S1.40-1984. For maximum confidence in your measurement results you can quickly compensate for local measurement conditions by calibrating before every measurement. Twin sound pressure levels guarantee definitive checks even in noisy environments, and ensure linearity in your microphones.
