It can be used in potentially explosive gas environments such as oil and gas platforms, refineries, chemical and petrochemical plants, pharmaceutical industry, power and gas processing industries.

The internal atmospheric pressure sensor allows measurement of relative and absolute pressure. It has three pressure module inputs, one switchable on the bottom and two digital on the side, allowing the user to change the calibrator configuration and easily meet most calibration and testing needs in virtually any environment.

The advanced transflective color touch display allows perfect data visualization even in direct sunlight, thus achieving a refreshing and intuitive user experience when compared to other competing equipment.

The ADT273Ex is a very portable tool, it accurately measures pressure with a switchable field pressure sensor and can also read current and mV produced by the transducers. It can also loop power transmitters during calibration.
The versatility of this calibrator is increased with the use of test applications incorporated by Additel.
