Reference Probes - Semi Standards
0 to 1300°C
Wide Temperature Ranges
Noble Metal & Type N for best life, stability and
reproducibility
Can be supplied with UKAS calibration
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 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.
Recommended 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.
Thermocouples
There is 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 Bloc
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.
