Our Story
Our expertise in constructing devices for plant gas exchange analysis goes back to Space Programs in 1960’s that aimed to develop technologies to utilize satellite images for predicting crop yields. These were followed by developing extremely precise gasometric and spectroscopy-based devices to measure photosynthetic processes. Roughly 15 years ago we focused on developing multi-cuvette whole-plant systems to measure plant gas exchange in various growth conditions.
