Dual-Channel Reference Thermometer Readout
Additel 282
OVERVIEW
Additel’s 282 Reference Thermometer Readout delivers the best possible accuracies and features in the palm
of your hand! With accuracy capabilities on par with laboratory grade thermometers, the ADT282 is capable
of handling even your most critical measurements. This ultra-high precision readout features dual analog
channels designed to facilitate comparison measurements and meet all of your temperature measurement
needs. The easy to use touchscreen makes navigating the well-designed menus a time saving and enjoyable
experience. The Lemo style smart connectors help to ensure that your probe calibration information is never
in question. The ADT282 Reference Thermometer Readout helps makes metrology simple and will quickly
become your new go-to when reliable temperature measurements are a must.

Reliable temperature metrology requires a stable repeatable measurement
device. The ADT282 supports stability and uniformity testing of liquid
temperature baths, thermocouple calibration furnaces, and dry well
calibrators. The highly accurate dual channels of the ADT282 support
deviation and uniformity studies. A very capable standard is required for
the measurement resolution of the thermometer readout in these situations.
The ADT282's superior measurement performance and dual-channel
conguration easily meet these measurement needs.
*Read up to two channels simultaneously

Main Features
Dual Channels
The model ADT282 includes dual inputs which provide support for a
multitude of resistive type sensors (RTD’s) as well as thermocouples (TC’s).
Both channels can be displayed simultaneously which allows for comparison
measurements and a host of other statistical analysis capabilities. And the
Additel 282 allows for easy differential measurement selection for T1-T2.

Sensor Library
Additel’s 282 Reference Thermometer Readout utilizes a ratio measurement
technology which provides an unmatched performance in stability and drift. In
order to ensure a very small temperature drift coefcient and reliable long-term
stability, the ADT282 uses current reversal techniques to cancel EMF effects
and a ratio technology to cancel the A/D converter offset. This highly advanced
technology has not been available in a handheld device until now!
In order to facilitate quick and reliable probe connections, the ADT282 has
been configured with smart connection ports for probes. Both channels
atop the reference readout utilize 6 pin Lemo style smart connectors for
RTD probes and mini-TC ports for thermocouple probes. The thermocouple
connection points utilize an imbedded temperature sensor which allows for
both internal and external cold junction compensation.With the smart probe
connectors, the ADT282 utilizes a user-selectable probe lock feature to pair
the probe with the channel it was calibrated with in a system calibration.
In order to improve the user's experience and speed of use, we have designed
a single touch menu option that navigates users to a control center panel. The
functions from the control panel include: Date, Battery status, Screen lock,
Bluetooth on/off, Speaker on/off, Snapshot, Smart diagnosis center button.
The ADT282 comes with standard Bluetooth communications capabilities
and is supported by Additel’s Mobile Link App. This very useful feature
will change the way you work as it provides a remote view of the ADT282
display at a distance, up to 20 meters on your personal mobile device.
Temperature sensors and instruments used in the field often require regular
calibration. In many cases, the disassembly of equipment can impact
productivity. Fixed sensors can be tested in process utilizing the ADT282
datalogging capabilities. In order to accurately monitor temperature changes, this
process may take several minutes or even hours to complete. ADT282 has built-
in powerful data logging function and supports multi-parameters data recording,
trend curve display, partial curve observation, statistical result viewing, data
storage capacity up to 8G to help with these applications.
The ADT282 has an extensive built-in temperature sensor library, including
ITS-90, CVD, Standard TC,13 types of industrial RTDs and 15 types of
industrial thermocouples, and also supports sensor customization. The user
can also edit the probe coefcients according to the ITS-90, CVD formulas
and the R0 parameter of the industrial RTDs. The extensive probe library
capabilities also support coefcient input methods for standard thermocouple
types.
