OVERVIEW
Additel’s new Multi-functional Documenting Process Calibrator series takes portability, functionality, and accuracy to
a whole new level and packages it with an intuitive and easy to use color touchscreen display. This series includes an
advanced documenting pressure calibrator (ADT227) and an advanced documentation process calibrator with a built-
in HART communicator (ADT227-HART). Additionally, each calibrator has an ATEX certified intrinsically safe option
(ADT227Ex) allowing you to perform calibration in the harshest of environments. We’re condent these new tools will not
only meet your calibration requirements but will make metrology simple for you!
Features
Easy-to-use Cellphone Like Interface
Additel's new and improved 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 ADT227 series brings an all new user interface to the world of process
calibrators. With a menu driven interface and a small size/weight, the ADT227
is the industry's smallest advanced multifunctional process calibrator with an
intrinsically safe version to boot (ADT227Ex). It adopts advanced human hand
engineering design for the most convenient eld handheld process calibrator
available.
The ADT227 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.

The ADT227 series delivers highly improved thermocouple measurement
capabilities by vastly improving the cold junction compensation(CJC)
specications and a much improved stabilization time.
The demands of remote calibration work can be challenging. The ADT227 series is
lightweight and highly portable and utilizes an advanced color LCD screen to help ensure
you can easily see, even in the (Ex) intrinsically safe versions.
All models in the ADT227 family have 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 condence in your critical calibration
and measurement work.
The Additel 227Ex series calibrators have passed the most stringent testing by
certified organizations to acquire intrinsically safe certificates, ATEX, IECEX.
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 transective 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.
The Additel 227 non-Ex version is equipped with “true effective
value” RMS measuring function, which can measure the RMS
of various waveforms with no need to consider distortion or
waveform parameters and other errors caused by various
waveforms

Additel 227 Series Calibrators come with a powerful documenting calibration task
application which provides a turnkey solution for automation and paperless calibration
management.
Tasks are easily created for temperature, pressure, flow and loop instruments. Up
to 10,000 documented tasks for ADT227 and up to 1,000 documented tasks for
ADT227Ex can be stored in the extensive on-board memory. Many tasks, when
executed, are fully automated in data collection and performance validation, such as
pass/fail and hysteresis calculations. All information can be integrated into Additel’s
ACal software for additional calibration management.
Automated Tasks for Paperless Calibration Management
The built-in full HART communicator will work with most HART transmitters . The
ADT227-HART contains an extensive DD library to meet the needs of your smart
transmitter. Our DD library is updated on a regular basis and at no additional cost.
The ADT227Ex-HART is integrated with basic HART communication functions,
permitting users to monitor, control, and calibrate HART instrumentations.
It's an ideal device for calibrating, maintaining, and troubleshooting HART
instrumentations.

The onboard applications provide a useful selection of features including HART communicator,
high static differential pressure mode, pressure leak test, safety valve test, analog transmitter
calibration, unit converter, thermal calculator, and snapshots to name a few.
High static differential pressure mode uses two sensors, unique calculation technology to
achieve a differential pressure measurement to 0.002% FS at high static pressures. The leak
test will automatically calculate the pressure drop to determine a leak condition. The safety
valve test is a specialized task which captures the exact pressure release point by taking 10
readings per second during a valve crack test.
You will nd this and much more as we continue to develop new apps at Additel.
Targeted application features
The ADT227 calibrator can record pressure, temperature and electrical signals.
Recorded values can be displayed numerically or graphically to identify trending. The
ADT227 & ADT227-HART can store up to 500 results. each result can include up to
100,0000 recordings and each recording can record a maximum of 7 channel values.
These results can easily be exported to Additel’s application software. Each log
session is easily congured at a set interval and provides a date and time stamp with
each reading.
Users can remotely connect mobile devices to the ADT227 via Bluetooth with
an unobstructed distance up 20 meters. The included USB type-C comm port
and cable provide a hard wired communication option as well as charging for the
removeable Li-ion battery, which provides up to 12 hours of run time.
In addition to all the great features mentioned above, the ADT227 series is loaded
with time saving features like our builtin 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 selftesting to help our customers get the very most out of their
investment in Additel calibration tools.
