Fluke P3011-MBAR-P Vacuum Deadweight Tester

Overview

The Fluke P3011-MBAR-P Vacuum Deadweight Tester is a precision pressure calibration standard designed for vacuum measurements in mbar units. It employs a suspended piston-cylinder design with ceramic piston and martensitic steel cylinder for excellent stability and repeatability. Traceable to NIST standards, it provides 0.015% reading accuracy (or 0.008% with PressCal software correction).

This model features an optional built-in hand pump for both pressure and vacuum generation, making it versatile for laboratory and field applications. The unit operates from 30 to 1,000 mbar with 10 mbar increments.
