TRP thermocouple calibration reference probe product description

**The temperature measurement of thermocouples requires a stable reference terminal. The common practice is to create a transition reference terminal by connecting copper wires to each thermocouple terminal. When the transition reference end is maintained at freezing point 0 ° C (32 ° F), the thermocouple output of the entire copper wire connected to the reading instrument appears stable and predictable. For accuracy and convenience, OMEGA offers the TRP series reference probe, which places the thermocouple copper transition reference end at the end of the ⅛ "diameter sheath for easy insertion into the TRCIII-A freezing point calibration chamber. Up to six TRP series probes can be used in the OMEGA freezing point chamber at once. When used in conjunction with a voltmeter and TRCIII-A ice point as shown below ™  When using a temperature millivolt table in the reference room, the reading can be converted to ° C or ° F.
