These thermocouples are suitable for use as references in Isotech Dry Blocks and for use with temperature indicators. These semi standards are lower cost and suitable for a variety of industrial applications.
The 935-14-91 is constructed from Platinum and Platinum Rhodium alloys and can be used to 1300°C. It has 1M of compensating cable terminated with a miniature thermocouple plug. The 935-14-88 is similar to the 14-91 but is made entirely from precious metals, with platinum wires all the way to the miniature plug.
There are a range of high quality mineral insulated metal sheathed (MIMS) Type N thermocouples. These devices are lower cost than the noble metal types and can be bent to a desired shape if required. They are suitable for use in Isotech Dry Blocks and for general purpose measurement and calibration applications.
