Kruss Bubble Pressure TensiometerPocketDyne
Features of the Bubble Pressure Tensiometer PocketDyne
The first truly handheld bubble pressure tensiometer.
For saving measuring data – the Dynamic Surface Tension – KRÜSS has equipped the device with a flexible memory, which saves the data even when the instrument is switched off. With this it is possible to transfer the measured data to a computer afterwards – particulary simple by use of the USB interface.
Extremely precise and inexpensive disposable capillaries made from inert speciality polymers minimize the effort of calibration and guarantee a high degree of measurement accuracy. You avoid the time-consuming and incomplete cleaning often required when using other instruments. Also, the depth of immersion of the capillary does no longer affect the measurement results- thanks to the smart use of modern technology for which KRÜSS has a patent pending. The measurement runs automatically, surface age or bubble frequency are adjustable over a wide range. Thus surface active material can be characterized fast - and complete compared with devices which offer just limited and fixed settings for surfage age. Default settings are either the real surface age or the bubble frequency, and not as other supplier offer, just the less significant “bubble lifetime”.
