Here’s what some customers had to say about the training course…

“The training I received was extremely well done. Lots of good practical information and hands-on learning led to my understanding the system well enough to teach others how to use it!” – Sue Dove (University of Georgia)

“The training provided by PP Systems was exceptional. The training covered aspects ranging from beginner user setup to advanced techniques of chlorophyll fluorescence. The step-by-step instruction made disseminating the knowledge gained with my other lab members quite easy.” – Lauren Pile (Clemson University)
