The Additel ADT227EX Intrinsically Safe Multi-functional Documenting Process Calibrator takes portability, functionality, and accuracy to a whole new level and packages it with an intuitive and easy to use color touchscreen display. The ADT227EX brings an all new user interface to the world of process calibrators. With a menu driven interface and a small size/weight, the ADT227EX is the industry's smallest advanced multifunctional process calibrator. It adopts advanced human hand engineering design for the most convenient field handheld process calibrator available.

The ADT227EX has been developed with a powerful embedded operating system which solves common problems of other designs including slow response, cumbersome key operation, high power consumption and overall slow processing.

Additel's ADT227 series provides much improved accuracies including an electrical accuracy of 0.005% RD + 0.005% FS, high-static differential pressure mode accuracy to 0.002% FS and across the board improvements in temperature measurement accuracies.

The demands of remote calibration work can be challenging. The ADT227EX is lightweight and highly portable and utilizes an advanced color LCD screen to help ensure you can easily see. The ADT227EX has been designed with ruggedness and dependability in mind and meet IP67 standards with a 1-meter drop test, 4G vibration, xenon exposure and 130g steel ball drop testing of the display.

Other environmental conditions have also been considered, such as temperature and humidity. To combat these external elements, Additel has designed a unique internal circuit design and process technology to allow for the utmost confidence in your critical calibration and measurement work.

The Additel ADT227EX calibrators have passed the most stringent testing by certified organizations to acquire intrinsically safe certificates, ATEX, IECEX, CSA and UKCA. The explosion-proof grade (Ex ia IIC T4 Ga), can be widely used in potentially explosive environments, such as oil and gas platforms, oil refineries, chemical and petrochemical plants, pharmaceutical industries, energy and gas processing industries.

Each intrinsically safe calibrator has an advance transflective color LCD display which has enhanced visibility when viewed in direct sunlight. No matter where your work takes you, these calibrators are up to the task.

In addition to all the great features mentioned above, the ADT227EX is loaded with time saving features like a built-in pressure and temperature converter, thermal calculator, wiring diagram guide for assisting with electrical connections, a built-in diagnostic center including intelligent alarm messaging and a real time error report and comprehensive self-testing to help our customers get the very most out of their investment in Additel calibration tools.
