If you frequently work with temperature calibration instruments, you know that a good dry-block calibrator is usually more than just a stable heat source. The Additel ADT875 series of dry-block calibrators combines excellent performance in terms of fast response, stability, radial and axial uniformity, and accuracy. Each device features a color display, dual-zone control, and many useful features.
But that's not all! The available "integrated process calibrator" option transforms the dry-block calibrator into a HART-capable, documenting process calibrator with a 3-channel thermometer readout.

Furthermore, the unique "CYOR" (Choose Your Own Range) option allows you to select your own temperature range within a standard range. The dry-block calibrator is optimized and calibrated in the factory to your selected measuring range, ensuring the best performance for your application.
