Dead Weight Tester - CPB5800

Brand: WIKA Alexander Wiegand SE & Co. KG

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.
  • Total measurement uncertainty to 0.006 % of reading.
  • Extremely flexible instrument with a wide range of single and dual-range piston-cylinder systems.
  • Dual-range piston-cylinder systems with fully automated changing between ranges.
  • Factory calibration includes traceability to national standards, as standard, with UKAS calibration possible as an option.
  • Fast and safe replacement of the piston-cylinder system via patented ConTect quick-release system as an option.
