These thermocouples are suitable for use as references in Isotech Dry Blocks, and for use with temperature indicators. Details of our laboratory-grade Standard Thermocouples with separate cold junctions can be found in our publication "Solutions for Primary and Secondary Laboratories".
These semi-standards have a lower cost, and are suitable for a variety of industrial applications.
The 935-14-91 is constructed from platinum and platinum-rhodium alloys. It can be used to 1300°C. We recommend it for the Pegasus 1200, and general purpose applications. 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 is a range of high quality, mineral-insulated, metal sheathed (MIMS) Type-N thermocouples. These devices cost less than the noble metal types, and can be bent to a desired shape if necessary. They are suitable for use in Isotech Dry Blocks, and for general purpose measurement and calibration applications.
The system accuracy or uncertainty will depend on the application and what instrument they are used with. The table shows the uncertainties that we can offer, with optional UKAS calibration from our accredited laboratory.
