I'm guessing there are many different types of thermocouples.  Or at least there are a few types.  A thermocouple is made from two different pure metals that touch together at one point where you measure temperature.  It matters which two metals you get.  I think you should find out which two metals are normally used on reprap printers and get the same type of thermocouple.

 

You connected the thermocouple to the two spots on the screw connector on the top of the UMO print head, right?  Did you tighten the screws down well?  It also matters I think what kinds of wires you use from the thermocouple to the connector - you have to use the same type of wire (e.g. copper for both wires).

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
