LabJack U12

USB Multifunction DAQ

The U12 is the original LabJack. The device is solid - the firmware hasn't changed in a decade, and it has a very long service record of reliability and customer satisfaction - all with an attractive price point. It can be used for measurement and control within simple analog and digital systems.

We continue to produce the U12 to support our customers who have integrated it into existing designs. For all new applications, we recommend the T4 or any of our other T-Series devices. This newer family offers faster speeds, greater hardware flexibility, and is supported by our latest cross-platform LJM API.
