acoustic calibrator / for sound level meters / portable / compact

Sound Intensity Calibrator Type 4297 is utilized for calibration of on-site sound-pressure and also verification of pressure-residual intensity-index.

One of the most significant and idle features of this device is that you need not dismantle the sound-intensity probe when it comes to measurements.

The calibrator is used with 2260 E Investigator™ sound intensity system enhancing the phase and it can also be utilized with sound intensity analysis systems based on PULSE™.

Type 4297 is a full sound-intensity calibrating device in one small, easy to carry unit with built-in sound resources. The acoustic feedback system itself positions for modifications in atmospheric pressure and completes the IEC 61043 standard.
