For use at high or low temperatures. The range the probe can be used in an oven is approximately 80K to 600K. If the sample only is heated the probe can be used for measurements up to 1000K although prolonged contact with the sample should be avoided. If a more limited range is suitable then consideration can be given to an adjusted version of the Jandel Cylindrical Probe which can be used at temperatures from 80K to 500K. Please note that the Macor Probe is not jewel guided.
