Options

PressCal Software

Windows-based software program that allows users to easily apply all necessary corrections to enhance the deadweight tester performance. Calibration details are then stored and/or used to automatically create a calibration certificate. PressCal is provided as standard with all 0.008% instruments.

Krytox

As operating fluid for liquid lubricated gas operated models.
