Please Help !

I'm constrained to use a type K thermocouple to measure temperature.  The thermocouples output has to be digitized but not displayed (it feeds into a data acquisition system).  I am willing to add an ADC to the data acquisition system, but I need some help going from the thermocouple to copper leads feeding the ADC.  Is there a single package solid state device that converts thermocouple signals to mVolts (that is, a device that has the compensation for the terminal dissimilar metals potential).  Or better








 yet, a simple and cheap pre-packaged thermocouple in / digital out board module.  I realize that equipment to perform the task is available from Omega, but I don't need the extra features and most importantly I can not afford the cost.
