Click here to download and try the fully functional Multi-Instrument software using your sound card as the ADC and DAC device!
Digiducer 333D01 USB digital accelerometer is the first fully integrated and ruggedized packaging of a high-resolution, broad-frequency piezoelectric accelerometer with integrated
internal digital data acquisition. When used in conjunction with the Multi-Instrument® software, the setup allows you to take reliable and quality vibration measurements as simply as
plug & play. No external power supply, data acquisition hardware, driver installation and manual entry of sensor sensitivity are required. It is a truly hassle-free portable vibration
test & measurement solution.
