Dry Well Calibrator
|
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 colour touch screen display, dual-zone control, and much more. You are just going to love these new dry wells! |
