A high-power electron diffraction unit, the KD-4 Electron Diffractograph, represents an evolution from an earlier unit, the KD-3. Some of the features include accelerating voltage of 120 Κν., ultravacuum range of 10"7 Torr, minimum beam diameter of 1 micron, ion etching attachments, temperature range of - 1 8 0 ° C. to 2000° C , and external manipulation of specimen in any plane.

Two calibration baths for precision calibration of resistance temperature sensors, thermocouples, thermistors, mercury thermometers, and other temperature sensors are low cost, small and portable, easy to prepare, and are designed for long-term performance. The Model 910-A shown uses a well-st irred, accurately-controlled silicon oil bath to provide calibration temperatures in the range batween —50° F. and + 5 0 0 ° F. The Model 911 uses a unique agitation assembly to aerate and maintain a calibration bath of water and ice at 32 ° ± .002° F. The calibration zone is uniform ± . 0 0 2 ° F.
