Measuring tempurture of a light source with a IR thermometer

[Fraser]

The function of a Pyrometer is the same, correct.

However the term Pyrometer when searching on the Internet will bring back results for all manner of temperature measurement devices that are not a modern Thermopile based IR Thermometer. It's a little like searching for an "internal combustion engine" when all you are really only interested in is the Diesel engine ! 

Pyrometer is an over arching category of test equipment that merely details that it is a thermal radiation measurement device.

Initially it appeared to be a different animal just adding to the confusion.

Indeed, there are many terms used. You can have 'contact pyrometers' as well !

I attach a range of Pyrometers for your interest 

As you can see, they come in many forms.

Scouring thru Amazon, I found many analog automotive gauges that came up using "Pyrometers" as the search entry.
