Callibration Equipment

M&G deadweight testers (primary standards)

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

M&G Type T series (hydraulic)

Range: 100 to 10,000 kPa (10 to 15,000 psi)

These high accuracy deadweight testers are ideal for laboratory or field use. The type T tester uses distilled water or fluid compatible with 300 series stainless steel and MONEL (including AAA tester oil). For applications up to 15,000 psi (1,000 bar). An optional dual piston lets you interchange piston/cylinder assemblies to extend the pressure measurement range using the same weight set. A kit is available for converting to a dual column tester.

M&G HL series (hydraulic)

Range: 100 to 22,500 kPa (10 to 3,000 psi)

This extremely compact, self-contained portable tester is designed for pressure ranges from 10-200 psi (1-15 bar) up to 50-3,000 psi (5-225 bar). Accurate to ±0.05% of reading, the unit features an easy-to-use screw pump with ratcheting handle and re-entrant type piston/cylinder assembly. This helps maintain accuracy as the test pressure increases. Weights and piston assemblies are interchangeable. The unit's AAA tester oil may be easily inspected through the transparent reservoir. Compact design in only 9 x 9 x 10 in (23 x 23 x 24.5 cm). Tripod option available for field applications.

M&G PK II series (pneumatic)

Range: 1 to 200 kPa (0.145 to 30 psi)

Low pressure tester, portable and ideal for field or laboratory use. The PK II tester is used for low pressure applications up to 30 psi (2 bar). Available in 7 engineering units: psi, g/cm2, kPa, bar, inH2O, cmH2O, and mmHg. This industry standard has an accuracy of up to ±0.015% of reading. Housed in a rugged case made for 'closed case' operation to protect from wind conditions. The tester base includes a built-in mounting for optional tripod use. Also available for medical applications ready for use with Oxygen.

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.

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 ±0.025% and a repeatability of up to ±0.005% of reading. Available in psi, kg/cm2, kPa and bar engineering units.
