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- Total measurement uncertainty to 0.02 % of reading.
- Factory calibration includes traceability to national standards, as standard; with DKD/DAkkS calibration possible as an option.
- High long-term stability with recommended recalibration cycle every five years.
- Masses manufactured from stainless steel and Aluminum, can be adjusted to local gravity.
