Works great

After some help from support, the CO2 sensor started working and our experiments are running! The manual needs to be updated a bit, and I didn't manage to receive a key through e-mail (only through support), but once everything was solved there were no issues whatsoever.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
