Series Dry Well Calibrators

Additel 875

OVERVIEW

If you are serious about portable temperature calibration tools, then you know a good

dry well calibrator is more than just a stable heat source. The Additel 875 Series Dry

Well Calibrators combine excellent performance in stability, radial and axial uniformity,

and loading with speed, ruggedness and portability. But we don’t stop there! The

Process Calibrator option adds the capabilities of a three-channel thermometer readout

and a documenting process calibrator. We’ve also incorporated a unique option to

select your own temperature range within the range of the model selected. We’re

calling this the CYOR option or Choose Your Own Range option. When you purchase

the CYOR option, you pick the upper and lower temperature range needed and we

calibrate and optimize the dry well’s performance over your selected range. Each unit

has a color touch screen display, dual-zone control, and much more. You are just

going to love these new dry wells!

Three models ranging from -40

℃

to 660

℃

Portable, rugged, and quick to temperature

Metrology-level performance in stability, uniformity, accuracy and loading effect

Dual-zone control

Full HART field communicator

Process calibrator option provides a multi-channel readout for a reference

thermometer, RTDs and TCs, task documentation , and HART communication

Process Calibrator Option

Each model offer has a Process Calibrator (PC) option. This process calibrator option combines the many features

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

the ability to measure a reference PRT and two devices 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 reading, conguring and calibrating HART capable

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 and a ramp 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.
