SMART Single: Compact Single-Point Vibrometer

Unlock efficiency with SMART Single+: The ultimate lab device

As part of the groundbreaking SMART series, the SMART Single+ is so much more than a laser Doppler vibrometer – it’s a lab in a device. Besides highly precise and non-contact vibration measurements without any retroactivity, the SMART Single+ is a multi-channel synchronous data acquisition device with built-in arbitrary signal generator.

It helps engineers, researchers and students to streamline their measurement process, eliminating the need for separate DAQ solutions or signal generators. With modularity as part of its DNA, the Single+ forms an expandable vibration characterization system, precisely synchronizing with any other SMART series device.

Even on its own, it improves efficiency by providing faster, optimized signal processing, better connectivity with other equipment using WiFi, Bluetooth and USB and a versatile 7-inch touch display to change all settings on the go. The integration of all these features in a radically compact design, combined with an intuitive yet powerful all-in-one software solution make the SMART Single+ the ideal choice for engineering, development and research.
