Additel ADT 226/227 Series - Multifunction Process Calibrators

Additel’s ADT226/227 Multi-functional Process Calibrator series takes portability, functionality, and accuracy to a whole new level and packages it with an intuitive and easy to use colour touchscreen display.

The ADT226 is a powerful but cost-effective process calibrator, available in an Atex – ADT226Ex certified intrinsically safe version to perform calibration work in the most challenging environments. While the ADT227 series includes an advanced documentation pressure calibrator (ADT227) and an advanced documentation process calibrator with an integrated Hart communicator (ADT227-HART). These ADT227 and Hart 227 are also available in Atex certified intrinsically safe version (ADT227Ex).

Additel’s ADT226 calibrator offers electrical accuracy of 0.015% RDG + 0.005% FS and many interesting features, such as a built-in barometer, dual-channel pressure module ports, high differential pressure mode with 0.002% FS accuracy, Wi-Fi, USB and Bluetooth communications.

The ADT227 calibrator offers the same outstanding features with an improved electrical accuracy of 0.005% RDG + 0.005% FS. The ADT227 also adds a comprehensive HART communicator, automated task management, data logging capability, and many other time-saving features. The ADT226, ADT226Ex, ADT227 and ADT227Ex all come with an easy-to-use colour touchscreen that can be clearly viewed indoors or outdoors.
