An acoustic calibrator is a device which produces an acoustic pressure of defined level and frequency. In other words, anacoustic calibrator provides a template of acoustic pressure.

By using such a reference we can check the accuracy of the measurements taken by the sound level meter and adjust themif a drift error in the sensitivity is detected.

Features:

•  SV 35A & SV 33A class 1 sound calibrators in accordance with IEC 60942:2003
• SV 34A class 2 sound calibrator in accordance with IEC 60942:2003
• Frequency 1 kHz
• 94 dB or 114 dB levels (SV 35A)
• 114 dB level (SV 33A, SV 34A)
• Built-in 1/2” MEMS reference microphone
• Microphone presence detection (SV 35A)
• Built-in temperature and static pressure compensation
• Automatic power off
• Dimensions 65 x 65 x 70 mm
