The KSV BPA-800P bubble pressure tensiometer represents the latest development in bubble
pressure measuring technology. Many of the key features are patented such as the
determination of bubble lifetime characteristics, the optimization of the aerodynamic
system, and the option to reach extremely short as well as sufficiently long measuring times.
Automatic operation and user independence are the key features of the KSV BPA-800P. Portability
and battery operation make the instrument extremely useful in industrial and environmental
applications. User friendly external PC software makes data analysis and storage easy.
