Applications of the dead weight tester

• Primary standard for calibrating the pressure scale in a hydraulic range up to 1,400 bar (20,000 psi)
• Reference instrument for factory and calibration laboratories for the testing, adjustment and calibration of pressure measuring instruments
• Complete, stand-alone system, also suitable for on-site use

Special Features of the dead weight tester

• 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

Description of the dead weight tester

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.

It has therefore been used for years in factory and calibration laboratories in industry, national institutes and research laboratories.
