THREE CHANNEL THERMOCOUPLE REFERENCE 
Model 885 Trio Three-Channel Thermocouple Referencing Unit

885 Three Channel Thermocouple Referencing Unit
The Trio Three-Channel Thermocouple Referencing Unit is a low-cost, accurate, portable unit designed to compensate three thermocouples for the variations in EMF caused by the cold junction not being at the standard reference temperature of 0°C.

Tables are available for each thermocouple combination which give the voltage versus temperature variation. The Trio senses the ambient temperature and generates an electrical voltage to cancel out the variation, thus providing equivalent of a 0°C cold junction reference bath.

Thermocouple Referencing Unit
  • 3 Channel Thermocouple 
    Referencing System

  • Accurate

  • Portable

 

The Trio Three-Channel Thermocouple Referencing Unit contains three electronic networks, incorporating a temperature-sensitive element which is thermally integrated with the thermocouple cold junction for maximum precision.

The Trio is manufactured to the highest standards and after assembly each unit is calibrated to ensure conformance to the relevant thermocouple table.

A wide range of thermocouple types are available. As standard, six thermocouple combinations are offered to customer requirements. The internal structure of the Trio allows either one, two or three thermocouple types to be compensated.
