For years, we’ve provided the most durable, accurate, quality pressure calibration products for field applications. The Additel 780S controller incorporates the same durability, accuracy, and quality into a new bench top controller packed with features and functionality that is remarkably easy to use. The Additel 780S offers two base ranges: to 1,000 psi (70 bar) and to 3,000 psi (200 bar). The base range establishes the maximum controlling range of the controller. Each configuration includes a control sensor in which you can preselect the sensor range best suited your application. External and internal sensors can be used which allows for expanded range and accuracy capability in the future.

Modular Design
Each unit comes with one Intelligent Pressure Module configured to the many range offerings provided. Standard accuracy sensors (ADT160A-CPXXX) are silicon pressure sensors with a 1 year accuracy of 0.02% FS. The precision quartz based sensors improve the 1 year accuracy specification to 0.005% of reading + 0.005% FS. Each sensor has been specially aged, tested and screened before assembly. After assembly each sensor is temperature compensated over the range of -10°C to 50°C. The Additel 780S allows for one internal pressure sensor and one external pressure sensor. The modular design of this unit provides for interchangeability of both the internal and external sensors with other Intelligent Pressure Modules.In addition to the Intelligent Pressure Modules, the Additel 780S has a built in barometric sensor. This allows for switching between gauge pressures to absolute pressures.

Standalone Solution
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 780S 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. Add the booster to the configuration and 3,000 psi (200 bar) is achievable with the Additel 780S controller series.

  • Pressure ranges from vacuum to 3,000 psi (200 bar)
  • Precision model accuracy of 0.005%RD + 0.005%FS
  • Standard model accuracy of 0.02%FS
  • Control stability of 0.003%FS
  • Easy-to-use icon based user interface

The 780S Pressure Controller is considered to handle a very wide range of applications which may normally require a pressure calibrator.

(3). Dependent on pressure module.

Barometric Measurement Specifications


Barometer range (60~110)KPa, the accuracy is 40Pa (11Pa is optional)

(1). 40Pa uncertainty (k=2) includes calibration uncertainty, linearity and long term stability (< 30Pa per year). Barometer range of 60 to 120KPa.

(2). Combined linearity, hysteresis and repeatability. Add 3Pa when used in gauge mode. When using the ADT160A-01-APXXQ sensors with the ADT780 controller in gauge mode, regular zeroing will realign the barometric reading to provide the most accurate result.
