GJX-2 Handheld Vibration Calibrator
It generates sinusoid vibration at frequency 159.2Hz. Can be used to calibrate vibration transducer. The frequency & amplitude of the vibration acceleration, velocity and displacement are all fixed so do not need any adjustment.
GJX-2 combines signal generator, power amplifier, standard transducer and a shaker in one and features a small size, high accuracy and easy operation. It can be used either for laboratory reference or on site verification.
It is controlled by 1 button for power on. After 50 second vibration, it powers off automatically. A green/orange LED for operation and low battery indication.
