If you are frustrated with with the options available for thermocouple calibration furnaces, the Additel ADT875 or AD878 are a good choice.
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 ADT875 Series and ADT878 Reference 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!
Process Calibrator Option
Each model 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, configuring 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.
Short Probe Kit
The Additel 110 series short probe calibration kit is designed to help users of our ADT875-155 (-40°C dry well) calibrate temperature probes and transmitters with short probe lengths.
