OVERVIEW
Additel's 273Ex is an Intrinsically safe handheld multifunctional pressure calibrator with a color touchscreen,
smartphone like interface, built-in quick test tasks and optional HART communications capability. This innovative
Additel product drastically improves explosion-proof field testing and calibration. The Additel 273Ex has a built-in
atmospheric pressure sensor, so that absolute pressure and the gauge pressure are easily facilitated. With three
pressure module inputs, one switchable at the bottom and two digital inputs on the side, the user can congure the
setup accordingly and easily meet the needs of pressure calibration and testing in virtually any environment.

A Modern User Experience:
Additel has gone above and beyond to provide our customers with the best possible experience when using this new
and revolutionary calibrator. The color touchscreen display provides a refreshing and intuitive experience compared to
other calibrators on the market. With an easy to navigate menu structure and fast touchscreen response, you will nd
the ADT273Ex calibrator simple yet powerful to use. The easy-to-read display isn’t just fun to use, but it’s built rugged
to handle the demands of a busy technician in the eld or the laboratory.
Optional HART Communication:
With support for HART communication protocols, the ADT273Ex Handheld Pressure Calibrator provides a pressure
calibration solution for transmitters over a wide pressure range. The ADT273Ex is a highly portable device and can
measure pressure precisely with a eld switchable pressure sensor, as well as read the current or mV produced by a
transducer. It can even supply an excitation voltage (loop power) to power sensors or transmitters during calibration.
Intrinsically Safe :
ADT273Ex has passed the most stringent ATEX, IECEX intrinsic safety certications from authoritative organizations.
The explosion-proof level is Ex ia IIC T4 Ga. It can be widely used in potentially explosive gas environments, such
as oil and gas platforms, refineries, chemical and petrochemical plants, pharmaceutical industry, energy and gas
processing industry. 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.
