Temp gauge accuracy

Here is a cheap thermal couple interface. It will work with a mulitimeter on 2V DC setting. They are nice to use because easier to remote see.

Here is one on ebay for less than $5. http://www.ebay.com/itm/CP7861-SUNPRO-TEMPERATURE-ADAPTER-FINDS-HOT-COLD-AREAS-u-/200808630571

I bought the meter cp7676 and adapter cp7861 years ago new for about $40. The meter is for automotive, does volts, Ohms, tach, diode test, and dwell.
