M&G deadweight testers (primary standards)
M&G HK series (pneumatic)
Range: 50 to 10,000 kPa (10 to 1500 psi)
High pressure tester for high pressure applications up to 1,500 psi (100 bar), AMETEK HK series testers operate in the same easy manner as the Model PK II and RK testers. HK testers feature an accuracy up to ¡¾0.025% and a repeatability of up to ¡¾0.005% of reading. Available in psi, kg/cm2, kPa and bar engineering units.
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
