I use LabJack hardware to make relative simple control instrumentation for research and teaching. The devices are very reliable and long lasting. I'm very happy using them.

Thanks. I'm using my new T4 as a greenhouse controller. Working great! Your docs are outstanding.

Software should be more intuitive.

Labjacks are a great way to get into automation. We used them extensively for our research to connect to sensors. Thanks to the Python API this is realtively easy and painless.

Hi we never have a problem with the equipment! But we only use as interface never use your software! Regards, Gabriel

Though the hardware works well, this company was (very) slow to support Python 3. I had to move on to something else that was more up to date.

Hi Joost, Sorry our expanded support didn't come fast enough for you. We have always support Python3 on LJM for our T-series devices but only added Python3 support in 2019 for our older legacy devices. https://labjack.com/news/python-3-update-labjack-ud-series-u12 Have you tried LJM yet? Let us know if you want a demo T-Series device.
