Wika Series 65-120 Portable Pneumatic Calibrator

The Series 65-120 Pneumatic Calibrator provides highdegree
accuracy for on-site testing and calibration service.
This versatile portable test stand combines precision
measurement and durable construction in a compact unit
that is capable of simulating, applying, holding, regulating
and measuring both pressure and vacuum. The dial, all
pressure connections, and the controls are panel-mounted
for easy access.
