"Employ U6 and T7 for my project"

I used both LabJack T7 & U6 with each of
-7 PCS of CB37,
- 2 * MUX80
-2 EI1034 Temperature Probe
-2 EI1050 Digital Temperature / Humidity probe
- 4 DB37 cable
to measuring 145 position temperature
80 probe for K Type thermocouple
65 semiconductor type LM35dz
in my Ph.D. project


I found it so useful except
1- the software cannot support to read more than 14 probe in easily way
2- using external probe as a reference junction for more accurate to measuring temperature by employing other probes because the heat source from the body of each U6 or T7 make a small deviation when depending to the internal reference probe and I hope to avoid this problem

I am happy to use LabJack product

"Where Function meets Flexibility"

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.

"Happy Labjack U3 user"

Labjack U3 user. Nice product, mature, available for a long time, performs as promised.

Definitely a good choice for PC-based data acquisition.

4 stars instead of 5 because the documentation could be better structured / more polished. Examples:
* Datasheet: no simple overview of the no of channels / channel types, a lot of scrolling through sections 2.6.x, 2.7.x and appendix just to have an overview of the no of channels + associated specs.
* Chapter 4: function calls are listed, but take e.g. 4.2.3 ePut -> accepts parameters -> takes some browsing to find out this can be used for e.g. quickSettling -> more browsing to find explanation in 2.6 for quickSettling
In the end all information _is_ available. But some short tutorial, or more documented example code right near the description might help.

"LabJack-of-one-trade does its dam job"

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).

"My T7 lab jack is my go to solution"

My T7 lab jack is pretty much my go to device for all things experimental. It’s easy to reconfigure and get useful data coming in and controls going out.

For more production work, we even have a few smaller jacks under our lab floors. Most people have forgotten they even exist, yet they don’t realize they depend on them every day.

I do wish the T7’s wireless security was more up to date for proper full 64 character WPA2 PSK pass phrases or (preferably) WPA Enterprise authentication. That’s my only real gripe.

"Excellent choice of reasonably priced…"

Excellent choice of reasonably priced data acquisition and control boards. It was an optimal solution for a project with limited funding and put together by university grad students. Very good support and access to resources as well. Thank you for putting out these DAQs. It is an excellent resource compared to very expensive DAQ solutions by large companies.

"Production Worthy but Turn On Delay is Annoying"

We have been using U3-LV & U3-HV in our low volume production, flash equipment for over a year and they have never failed. The only gripe I have is the turn on (wake up) time had caused us some annoying race issues with the software that we wrote to communicate with them when they were powered up when we were developing the software.

"LabJack has been a great company to…"

LabJack has been a great company to work with. Getting spun up on my automation needs was quick and simple.

Thanks for the years of service.

"Experience with LabJack U6"

I used the LabJack U6 to measure mainly currents and voltages on historical locomotives for comissioning and troubleshooting.
I used LJStreamUD, this SW is easy to understand and works perfectly.

"I'm the happy owner of 1 Labjack 12…"

I'm the happy owner of 1 Labjack 12 (bought in 2008), several UE9 and U6 and one T7.

The U6 and T7 are very accurate in voltage measurments (as a 10000 points voltmeter), and, as far as I could test, very stables.

I used them in :

- improvised temperatures measurments with platinium RTD in factory conditions,
- real time displacements (LVDT) and pressure measurments in factory conditions.
- thermocouples, speed measurments, frequency and pulse generations in bench conditions.

Those device are very versatiles, and well documented. Most of the time I found answers on the Labjack site. On some other few time, I could check the live support, wich is very "reactive" (firmware upgrade to correct bug in a few days).

In association with Daqfactory, it is possible to build an application very fast, with data logging, graphics, and sophisticated computations.

I also used the drivers for UE9, U6 and T7 to build measurments applications with Embarcadero Delphi IDE.

Compared to other industrials devices with equivalent capabilities, the price of Labjacks is very attractive.
