  • Julien GUILLORY
    Our team mainly uses software integrated in the NIR spectrometers and we needed a broader vision to go further in our model developments. The contact was really easy and interactive. Ondalys was able to respond to our requests, adapt the training session to our needs, our data sets and our issues. Expertise, professionalism and good humor make a good recipe at Ondalys!
