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

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.
