Keterangan

The generator noise level 9101/ HD HD 9102 is a portable, battery-powered sound source, suitable for calibration of sound level meters ( portable and laboratory) and acoustic
measuring stations. And ‘ possible to calibrate directly microphones 1 / 2 “ of mechanical dimensions conform to the requirements of IEC 61094-1 ( “ Measurement Microphones, Part 1: Specifications for Laboratory Standard Microphones” ) and IEC 61094-4 ( “ Measurement
Microphones. Part 4: Specifications for working Standard Microphones)

ADVANTAGES OF CALIBRATORS HD 9101 / HD 9102 ARE:
- With the frequency of the sound signal at 1000Hz can perform calibration of sound
level meters with any frequency weighting ( LIN, A, B, ...) , without introducing correction factors.
- The sound pressure level generated is independent of atmospheric pressure is therefore not necessary to correct the value function of atmospheric pressure.
- The calibrator 9101/ HD HD 9102 can be conveniently used in both laboratory and field.
- Ease of use allows the use even by unskilled personnel.
