Good product!
It works the way that I expected, although I did buy this product 9 years ago, it is still working well. Thanks!

Our experience with LabJack technical support was great. They helped us quickly identify the root issue of a problem we were having. We were very pleased with their service and would highly recommend their products.

Great service
By greg.brown
The LabJack is flexible, powerful and pretty bulletproof. What I like most is that it hits a sweet spot in terms of capability, flexibility and price. I use it in a research setting for control and automation of experiments involving thermal chambers, fluid loops and heat transfer measurements. I've used it in both mechanical lab and wet-lab settings. The T7 is basically my testing swiss army knife. In all my setups, the T7 was never the failure point or bottlekneck.

Simple programming, very good for small application using few I/0

LabJack is the best. Simple yet flexible DAQ control. Excellent user manuals and support forums available. Responsive engineering support from LabJack.

I got a labjack u3-hv system because it's probably the best bang-for-your-buck out there when it comes to ready-made DAQ systems. The documentation was good enough that I was able to interface it with matlab and figure everything out in a couple of days. I would definitely recommend LabJack systems to anyone (and definitely hope I get the chance to use the higher-end systems someday).

Hi Mdflood, Thanks for the kind words. Glad the U3 worked well for your application. Let us know about your next application that will leverage the power of the T7 or stay tuned for even more powerful device to come...
