937 100-Channel Thermocouple Referencing Junction System
The TRU 100 Temperature Reference Unit supplies a stable and accurate 0°C or elevated Reference Temperatures between 45ºC and 70ºC.
It is a self-contained all solid state unit using peltier technology which provides maintenance free operation. 
The TRU 100 features rapid cool down from high ambient temperatures and is stable within 10 minutes from switch on.

• Thermocouple Referencing to ISO9000 
  at 0°C in Ambient Temperatures up to 65°C
  or elevated reference temperatures
  between 45ºC and 70ºC

• References Up To 100 Thermocouples

• Pre-wired Thermocouples, Compact Design

• The TRURAC Combines Two TRU 100 in a 19” Rack-Mount Enclosure for the Referencing of 
  Up To 200 Thermocouples

An alarm will be activated should the reference temperatures deviate by more than the user definable span. Thermocouple Reference Junctions are located in a reference block and connected to their marked input and output terminals in an isothermal enclosure. 
The uniform temperature throughout the enclosure ensures that no thermoelectric EMFs are generated at the terminals.
One advantage of the TRU100 is that the user need not be concerned with the supply and installation of reference junctions since it is only necessary to connect the thermocouple compensation cables to the input terminals and the measuring instrument to the output terminals of the TRU100.
