Kibron DeltaPi > standard configuration

Base mechanics

33 x 14 x 6 (h) cm ( 13 x 5.5 x 2.4 inches)
0.85 kg ( 1.8 lbs)

Electronics

27 x 23 x 8 cm (10.6 x 9 x 3.1 inches)

Total weight

2.8 kg (5.9 lbs)

Principle

Wilhelmy method using a small diameter ( 0.51 mm)
special alloy wire. No artefactual hysteresis as when
using the conventional Pt-plates. No drying and
accumulation of salt which cause significant errors
when filter paper is used.

Dynamic range

0 to 130 mN/m

Resolution

10 µN/m

Temperature sensor

Automatic monitoring and display of temperature
in the course of the experiment, resolution
0.1 degrees (optional feature)

Materials

Metal alloy and high purity PTFE. Several designs available.
Also user-defined designs are routinely made. 

Volume

300 µl in surface pressure measurements.
Subphase can be magnetically stirred.
