# Thermocouple voltage compensator

Hey,

Yea, however I am trying to get away without needing one of those meters because they are not so cheap. =)

Just want to be able to use them reliably with a voltmeter or other meter without an ice bath for reference.

Ok, I don't know of anything else that does this automatically. Why don't you want to measure your reference temperature with something like a thermistor, then compensate manually?

What temperatures are you going up to? If it is less then 200 deg c you could try using an RTD.

Yea, well the reason is that I happened upon some thermocouples for free (well not free, but I was never re-imbursed for them as planned so after the experiment I kept them), and just want an easy way to use them.

I am basically looking for a cheaper version of this:

It's just a substitute for onboard circuitry. It would allow me to use a voltmeter and not worry about a reference temperature for measurements.

How accurate do your measurements need to be?

No requirements, but preferably from 1-3 degrees C at the worst.

The cheapest option is probably to check the cold junction temperature with a thermometer.
