Description
Pressure balances (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments.
The direct measurement of the pressure (p = F/A), as well as the use of high-quality materials enable a very small measurement uncertainty, in conjunction with an excellent long-term stability.
Features- Measuring ranges (= Static-Pressure + differential pressure) up to 400 bar (5,000 psi) pneumatic, up to 1,600 bar (23,200 psi) hydraulic.
- Total measurement uncertainty to 0.008 % of differential pressure plus 0.0001 % (1 ppm) of Static-Pressure.
- Factory calibration included as standard, traceable to national standards; with DKD/DAkkS calibration possible as an option.
- High long-term stability with recommended recalibration interval every five years.
- Masses manufactured from stainless steel and Aluminum, can be adjusted to local gravity.
