4.1 Description
With the Model CPH7600, Wally Box III, WIKA offers a further development of the well-known
Wally Box I and Wally Box II. The Wally Box III is a compact, portable pressure calibrator, which
has been designed for mobile use as well as for stationary workshop and laboratory testing. A
special feature of this test instrument is that it is fitted with two independently- operating pressure
systems. One pneumatic system is designed to be supplied from an external pressure supply,
while the supply pressure of the second system is generated by the integrated electrical pressure
generation. This enables the user to perform different measurement tasks or calibrations,
regardless of external pressure and power supplies.
