For years, Additel have provided the most durable, accurate, quality pressure calibration products for field applications. The ADT 780 series controller incorporates the same durability, accuracy, and quality into a new benchtop controller packed with features and functionality that is remarkably easy to use. The ADT 780 series 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 which is preselected to the sensor range best suited for your application. External and internal sensors can be used, this allows for expanded range and accuracy capability in the future.
