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.

Hi Homrig, would love to hear more about this application! Can we get some pictures and share cool pictures of a LabJack on an old steam train? Email us [email protected] our team would love to nerd out!

Our operations team rocks! When you don't outsource your shipping (Amazon or 3PLs) and treat people as they want to be treated it is amazing how quickly you can ship orders and still keep the customer smiling!

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.

Don't even know where to start... thanks for all the fine words and your support over the years. You must be a LabJack super user, it sounds like you have owned and work with every device we sell! DAQFactory is great and is so easy to suggest to our customers. Glad to have you as a customer.
