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 - 1K E-Pump Electric Pump

Additel ADT 780 Benchtop Pressure Controller provides a standalone solution with pressure ranges from vacuum to 3,000 psi (200 bar). The ADT 780 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. 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.

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