VC21 Vibration Calibrator

Product Description

The VC21 is a multi-frequency and multi-amplitude reference shaker. The microprocessor based unit contains an amplitude control loop with a reference accelerometer built into the shaker head. Its lowest frequency of 15.92 Hz makes it suitable for the calibration of whole-body human vibration meters to ISO 8041 and other low frequency applications like measuring equipment for building vibration. Operation is very simple by four push-buttons, two for amplitude and two for frequency. A bright OLED display shows frequency and amplitude, the amplitude error in percent and the battery condition. The strong electrodynamic shaker allows heavy test objects up to 500 grams. The built-in NiMH accumulator lasts for approximately 5 hours of operation. A cast aluminum enclosure protects the instrument under harsh field conditions.
