Neat idea, tell me more....
* Contact info for Omega Engineering?
* Others who sell them?
* Why would the multimeter have to "accept thermocouples"? All thermocouples
will produce a voltage based on a temperature delta -- and all multimeters
can measure voltage. Or is it just that the multimeter must be able to
read fairly small voltages? Or that the multimeter has a temperature display?
* I assume this will work best where you are just looking for relative temps
(like inside of tire vs. outside), but not so well if you want to know the
actual temp? Or is it the case that the thermocouple probes are calibrated
in some way to allow you to know the absolute temperature?
* Are they linear through the important temperature ranges?
* What temperature ranges do the thermocouple probes allow you to read?
* What other disadvantages do they have relative to a purpose-built pyrometer?
Thanks,
Brian
