NEW 9110D Portable Vibration Calibrator (with USB port)
Modal Shop Portable Shaker Vibration Calibrator
The 9110D is a compact, battery-powered and completely self-contained vibration reference source which can be conveniently used to calibrate individual sensors, vibration switches, as well as to validate the entire measurement channel.

The 9110D calculates and displays test sensor sensitivity on the readout screen in real time. It also has built-in ICP® input for common piezoelectric accelerometers. In addition, users can now save up to 500 calibration records directly to the unit's internal memory. These can also be copied or transferred to the included USB flash drive with Report Generation Workbook via the unit's USB port. The saved data can then be transferred to a computer and an ISO 17025-compliant  customizable Calibration Certificate generated and printed.

Frequency range : 7Hz to 10kHz
amplitudes : up to 20g (196m/s2)
