OVERVIEW

We understand the many challenges associated with thermocouple calibration work. That is precisely
why we decided to introduce the ADT875-1210 and ADT878-1210 Thermocouple Calibration
Furnaces.

With an unmatched stability, uniformity and an optional on-board process calibrator, calibrating
thermocouples has never been easier. With two separate units to choose from, the ADT875-1210 and
ADT878-1210 furnaces include a patented multi-zone temperature control which provides a never
before seen, highly stable and uniform heat source to ensure you get the best possible results from a

modest investment. With metallic interchangeable inserts, users have the exibility needed to service
a wide variety of UUT’s and the durability they have come to expect from Additel. The ADT875-1210

and ADT878-1210 can be purchased with or without our on-board process calibration electronics to

provide exibility for customers who are needing the best 1200°C heat source on the market.

If thermocouple calibration and/or verication work is part of your workload, you don’t want to miss out

on this opportunity to save valuable time and money with these best in class furnaces from Additel.

Temperature Control

The Additel ADT875 & ADT878 Thermocouple Calibration
Furnaces have been designed with a unique and innovative
way of controlling temperature and temperature gradients.

We like to call it “Advanced Adaptive Control”. This exciting

new design feature incorporates our patent pending wind
tunnel control technology with Additel’s impressive 3-zone
temperature control to provide the very best uniformity and
stability possible.

Each ADT875 & ADT878 is tested and calibrated in Additel’s

Temperature Calibration Equipment

accredited laboratory (Brea, CA) to ensure that each unit
is ready to go when the customer opens the package. The
included accredited calibration certificate provides data
relating to accuracy, stability and uniformity to help provide
even more confidence in the testing and calibration of each
and every ADT875 & ADT878 Thermocouple Calibration
Furnace.

Process Electronics

Both the ADT875 & ADT878 can be ordered with Additel's Process Calibrator
(PC) option. The Process Calibrator Option combines the many features found
in a thermocouple readout device and process calibrator with the ADT875 &
ADT878 Calibration Furnaces.
This unique option includes Additel’s patented Quick-Push connectors which
accommodate virtually all TC connection types. The process option also
includes the ability to measure a reference grade thermocouple and up to
(4) under test channels. Channels 1 and 2 can measure mA, voltage, perform

Temperature Calibration Equipment

switch testing and source 24V DC. In addition to these measurement functions,
the process option provides full documenting capability of creating tasks, saving

"as found" and "as left" results and HART communications for simplied

transmitter work. The snapshot feature allows users to capture all information
displayed on the screen with a touch of the screen. This optional add-on allows
for data logging of all channels using our auto step and a ramp functions.

By utilizing the external reference option users can select to control to the
furnace set point using an external control probe, which helps to reduce
uncertainties. The external control probe feature also facilitates the

handy self-calibration feature!
