Class I Noise Meter / Sound Meter Calibrator incl. ISO Calibration Certificate
for mobile use / For various evaluation filters / Accuracy IEC 942, class 1 / For microphones with different dimensions
The Noise Meter / Sound Meter Calibrator is a battery powered sound source. With the Sound Meter Calibrator, direct and fast calibrations of sound level meters and other systems for noise measurement can be carried out. Sound level sensors of 1, ½ and ¼ inch can be connected to the Sound Meter Calibrator and checked via the adapter attachments.
The calibration frequency for the Sound Meter Calibrator is 1000 Hz. This is the reference frequency for the internationally standardized evaluation curves. With this Sound Meter Calibrator you can calibrate sound measuring devices with weighting filters A, B, C, or D. The calibration pressure for this Sound Meter Calibrator is 94 ± 0.3 dB (1 Pa) and 114 ± 0.3 dB (10 Pa). Thus, the Sound Meter Calibrator is used in quality assurance, for example, to test sound level meters or in calibration laboratories.
