For years, Additel have provided the most durable, accurate, quality pressure calibration products for field applications. The Additel 780 controller incorporates the same durability, accuracy, and quality into a new bench top pressure controller packed with features and functionality that is remarkably easy to use. The Additel 780 offers two base ranges: to 7,000 kPa and to 20,000 kPa. The base range establishes the maximum controlling range of the pressure 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. Quartz Pressure sensors have an accuracy to 0.005% rdg, +0.005%FS and standard modules 0.02%FS allowing you to mix and match ranges and accuracies for you own requirements.
