This equipment gave insights I couldn't get via coupon testing. I use it daily!

Rating: 5.0 5.00 Out of 5 Stars

Organization: Anonymous Company

Application Area: Corrosion testing.

"Historically we only leveraged coupon testing. I came in contact with the Gamry equipment after a Penn State corrosion short course. I leveraged a nearby corrosion lab to generate some results and concluded a few months later this equipment definitely has the right capability for my needs, of fast and predictive corrosion understanding. The order and set up in our lab went really smoothly and happened in partnership with the vendor over 3 days of training. Following the training the supplier offered a question and answer period of two weeks to ensure all went fine, and I submitted a few questions and received great help. Given the great partnership with the vendor the implementation, ease of use and after sales support turned out to be most successful. I wish I had bought and implemented it earlier."

Great instrument, worth the money

Rating: 5.0 5.00 Out of 5 Stars

Organization: USC

Application Area: electrochemistry

"Reference 600+ is easy to use and highly reliable. Also it looks a lot better than the old 600 series."
