Pressure Calibration Standards

Our high performance range of deadweight testers and pressure controllers for maintaining pressure calibration standards includes products from manufacturers such as Additel, Aremeca and Ametek. The outputs of these devices are compared at one or more pressures, typically from the lowest to highest readings of the DUT’s full scale range, or the range for which it is normally used. This comparison process is performed in a chain from the highest level of fundamental pressure realization.

Additel ADT 780 series - Pressure Controller

New Precision accuracy models with 1-year uncertaincy to 0.01% of reading
The Additel 780 series controller incorporates Additel’s renown durability, accuracy, and quality into a new bench top controller packed with features and functionality that is remarkably easy to use. The Additel 780 series offers two base ranges: to 1,000 psi (70 bar) and to 3,000 psi (200 bar).

  • Pressure ranges from vacuum to 3,000 psi (200 bar)
  • Removable interchangeable intelligent sensors
  • Precision accuracy models to 0.01% of reading
  • Standalone solution to 1,000 psi (70 bar), no gas bottle required when used with the Electric Pump
  • Standard model accuracy of 0.02% of full scale
  • External pressure modules to 3,000 psi (200 bar)

Additel ADT 780 - 1K E-Pump Electric Pump

Typical pressure controllers will require a nitrogen bottle for the gas supply which make it difficult to move the controller around without having to move or connect to another bottle. The Additel 780 series is unique in that with the optional electric pump, you can generate pressures to 1,000 psi (70 bar) without the need of a gas bottle.

  • E-Pump generates from vacuum to 1000 psi (70 bar)
  • Built-in filter and liquid trap
