Probes are suitable for use with all Isotech thermocouple reference units or may be used with any other equipment including ice flasks and ice point reference units.
They can be supplied to suit a single thermocouple, or up to ten double junctions in a single assembly.
These probes are normally specified to order, or are made to match the reference equipment to which they will be fitted. Normal lead length, L2, is 1M but can be specified at the time of order along with the probe length, L1.
All wire material is to the highest grade available and PTFE insulated, numbered and colour coded for the appropriate thermocouple type. Double junctions are most commonly supplied (four wire connections per junction). Single junctions (two wire connections per junction) can also be supplied.
For Types R & S cold junctions are most commonly made from low cost compensating cable but can be supplied in platinum material to special order.
Standard thermocouple Types are, K, E, J, T, N, U, S and R. Other materials available on request
For Isotech reference units simply advise which model the junctions are for, and the types and number required. For custom junctions the following information is required.
