Theoretically, building a tensiometer is simple: putting a moveable sample stage underneath a force measuring device. But developing the best-in-class tensiometer is something completely different. It takes more than just using an utterly precise force sensor (which we did) and the sample positioning with the widest dynamic range (which we developed). It takes a change of perspective that focuses on the user and his task – you and your task. It takes the will to make your lab work as convenient, flexible, and time-saving as possible. We believe that Tensíío is that kind of instrument.
