Reference Dry Well Calibrators

Additel 878

OVERVIEW

We are taking temperature calibration to the next level with the Additel 878 Reference

Dry Well Calibrators. If you are looking for the best dry well on the market, then look

no further! Additel’s commitment to continuous improvement, quality and time saving

features are on full display in the ADT878 series. With three models to choose from,

ranging from -40 to 700°C, you will nd the perfect t for your calibration needs. The

Process Calibrator option adds an external reference input, a two-channel readout for

UUT’s and a full complement of capabilities to help with everything from measuring

temperature sensors, to calibrating thermocouples, self-calibrating the Reference Well

and conguring HART transmitters. Each unit comes standard with a large touchscreen

display, dual-zone control and Additel’s commitment to the best customer service in the

industry. We are certain that you will be blown away by the outstanding performance

of these game-changing Reference Dry Wells!

Process Calibrator Option

Each model can be purchased with our Process Calibrator (PC) option. This option combines the many features found

in a fully functional HART documenting process calibrator with the reference grade dry well. This option includes the

ability to measure a reference PRT, with virtually any connection type, and two device under test channels which can

measure, mA, voltage, switch, RTD or thermocouple. In addition to these measurement functions, this calibrator has

full documenting capability of creating tasks, saving as found and as left results, as well as communication with HART-

smart transmitters. The process calibrator option also has an on board full HART communicator which allows users to

read, congure and calibrate HART transmitters. The snap shot feature allows you to capture all information displayed

on the screen with the push of a button. This optional add-on allows for data logging of all channels on an auto step

function. By utilizing the reference PRT, you can select to control to the dry well set point using the internal sensor or

the external reference PRT.

We believe using an external reference probe as your standard is the best way to perform your temperature

calibration. But we also recognize this method is not always necessary or convenient and depending on the

application, using the internal control sensor would be preferred. Traditionally, the internal control sensor has a wide

accuracy which can largely be contributed to its long-term drift. We’ve built-in a self-calibration feature allowing you to

run an automated calibration of the internal control sensor using your external reference. With literally a few selections

the calibration will run automatically giving you a fresh, traceable calibration of the control sensor which will improve

its accuracy as you will not have to account for its long term drift when used as the reference.

Self-Calibration

Process Calibrator

Optional Electronics

Traditionally, dry wells were simply a stable heat source. To enhance the usability of our Reference Dry Wells, we've

added automation features enabling you to utilize these amazing devices as a highly stable heat source, triple point of

water maintenance apparatus, and annealing furnace.

Combined with the ADT878-TPW-KIT, the ADT878-160 Reference Dry Well can be used to automatically realize

and maintain a triple point of water cell. Traditional methods take time and practice to realize the triple point of water.

Additel has now simplied this process with an automatic TPW realization feature. Simply insert the cell and PRT into

the Reference Dry Well and run the procedure. The automation in the rmware will alert when the cell is super cooled.

Remove the cell and give it a shake and now you can maintain the triple point in the reference well. This is very useful

to check the drift of your PRT. For more information, please see our ADT878-TPW-KIT data sheet.

When you purchase our 700°C Reference Dry Well, you will find our automatic annealing feature used to anneal

PRTs. We have precongured annealing procedures that set the temperature annealing time and cool down rate. This

feature, also lets you create your own annealing procedures.
