Wallybox III - Mensor Model CPH7600 Digital Pneumatic Calibrator

Welcome to Mensor a part of WIKA Alexander Wiegand SE & Co. KG

Wally Box III Pressure Loop Calibrator DISCONTINUED - See CPH7650

cph7600 Since 1969 Mensor has been designing and manufacturing precision pressure measuring and pressure calibration instruments and systems. From the very first quartz manometer designed for the aerospace industry, to the modern CPC 6000 Automated Pressure Calibrator of today, Mensor, now a part of WIKA Alexander Wiegand SE & Co. KG, specializes in providing quality pressure products and services to a wide variety of industries around the world.

Mensor is now manufacturing the Wally Box III (CPH7600) as a replacement for the 65-2000 and 65-2000-II

Dirt Trap
Mesnor calibrator dirt trap

The Wally Box III should only be used with dry and clean test items. Soiling of the integrated pump, for example, through contaminated test items, can lead to faults on the pump or require the pump to be cleaned. By using the dirt trap specifically developed for the Wally Box III, contamination of the integrated pump can be prevented.
