Dead Weight Testers
Technel Engineering features the DH-Budenberg line of dead weight testers and pressure balances. These units represent the best in uncertainty specifications for a wide range of operating pressures. Pneumatic, hydraulic and differential testers are available from 1500 to 70000 psi. The total measurement uncertainty is as low as 60 ppm of reading to provide the best in pressure calibration. These compact units are also portable for the ultimate in flexibility for laboratory or field calibration applications.

The new Mensor CPD8500 digital deadweight tester is an instrument that combines the performance of a manual pressure balance with the efficiency and usability of a compact digital primary standard. The CPD8500 digital deadweight tester is housed with an internal environmental monitoring module, a head temperature probe and a precision vacuum transducer for automatic detection of sensitive parameters. An optional internal or external barometric reference provides versatility with gauge or absolute pressure modes. Features and Specifications: • Pressure Ranges: 2...20 bar abs (29...290 psia) and 1...500 bar gauge (15...7,250 psig) • Accuracy: 35 or 50 ppm (0.0035% or 0.005%) of Reading • Standard Interface: Ethernet, IEEE-488, USB, RS-232 -
CPU 6000 Calibration Unit Provides critical on-line data to provide the best uncertainty value of the pressure balance. Computes air density from ambient humidity/temperature/pressure Measures piston temperature and floating position of the masses Calculates Mass to Pressure and Pressure to Mass conversions
