M&G deadweight testers (primary standards)

M&G RK series (pneumatic)

Range: 1 to 2,000 kPa (0.145 to 300 psi)
Accurate up to ±0.015% of indicated reading, this primary standard is ideal for pressure ranges from 1 to 300 psi (0.01 to 20 bar) and provides for incremental pressures down to only 0.1 psi (1 mbar). Available in seven different engineering units: inH2O, psi, kPa, cmH2O, inHg, bar and kg/cm2. Features a cast metal base with quick levelling for field or laboratory use. Also operates with cover closed.

Deadweight testers are superior to all digital systems. Use the deadweight testers as your company's primary standard or to calibrate very critical pressure gauges as in custody transfer applications.

In 1966, Mansfield & Green introduced the deadweight tester based on the “floating ball” principle. This deadweight tester is an extremely easy-to-use, reliable and accurate primary standard and is now earning its reputation as the “standard of standards”.

Typical deadweight tester applications are:

• laboratory or field use
• hazardous locations
• critical process control loops extending the time between calibrations due to better accuracy and uncertainty
• calibrating instruments on custody transfer stations thereby reducing the uncertainty of the measurement
• calibrating portable digital calibrators to achieve the highest possible accuracy and reducing maintenance costs
