LabJack Avis 

Excellent data loggers
They are really easy to use, and lots of software options are provided to get started quickly, or do more advanced automation. I love that they even sell OEM versions to integrate into your own test beds.

Exceptional support - have always been impressed by the their willingness to address all kinds of issues.

I appreciated the contact and encouragement your emails provided.

As I purchased my device from a local supplier in addition to signing up with LabJack, some of the information came well before the device did.

I appreciate the information, FAQs etc. available on the LabJack web site. I also like the way drivers etc. are provided for down-loading.

As a distributor for your products for 10 years I can say you have been fantastic.

We needed a USB device for data collection and this product worked flawless ly the first time we set it up. Great product

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.

very good device, stable, never fail

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

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!

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.

Data acquisition is quite unreliable, you have to deal with buffering, delays and even unpacking the data yourself by studying the APIs. For example, if you acquire more than one channel, all your data is still in one array 1xn and you have to turn it into a matrix nchannels x time by yourself. Another example, every time you extract a chunk of data in its buffer you need to query with another call how many samples are still stored in the Labjack buffer and offset the delay by an amount proportional to the leftover samples (whose number varies at every call). It's a nightmare. Engineering projects are quite difficult in themselves without having to re-engineer even the basics such as data acquisition, which is what Labjack should claims to do, reliably and out of the box.

I needed an inexpensive, accurate device to help me develop an analog control and I found the perfect one here. Easy to set up, develop a program and a working prototype in a few weeks. Very happy with the accuracy and ease of use.

My 600$ unit failed and I replaced it by a much simpler and much cheaper solution. A teensy arduino for my data acquisition. Never buying your overpriced stuff again

Perfect service, no issues at all

I was new to LabJack products and not familiar with much of the terminology used. After only a few emails, I had all the information I needed to connect 12 thermocouples up to a T7 using a Mux80 and two CB37 cards. The information available on the web site is very, very helpful, especially the guides. Hardware and software both are great.

Email response to my questions were always same day, usually within a few hours. I chatted online once and the person who helped me knew the answers and was very courteous.

Overall, I am very satisfied with LabJack.

LabJack offers great products and service and support.

A LabJack U12 unit failed some time ago, probably my fault, and it was
repaired quickly and returned to me, no questions asked, no charge.

You can count on LabJack.
