K-type thermocouples are often in that range and aren't horrifically expensive. Some multimeters have a socket for a thermocouple- and can display the temperature on the multimeter screen- so this can be a cheap way of getting a temp probe (I use this for one my kilns- http://www.screwfix.com/p/philex-83002r-s-digital-multimeter-with-temp-probe/88381. I'm in the UK but I'm sure similiar things can be found elsewhere!).

Does anyone have a source for high temperature infrared thermometers reading >3000F that don't cost an arm and a leg. The stuff I'm looking at are industrial strength with a price to match $$760-$2650. Owww Way too much for a hobbiest!

What about that? http://www.ebay.es/itm/TERMOMETRO-LASER-DE-MANO-INFRAROJO-IR-LCD-THERMOMETER-TESTER-PISTOLA-GUN-DIGITAL-/300973039441?pt=LH_DefaultDomain_186&var=&hash=item4613641f51

They have different ones with prices depending on range. I'm thinking on the -58 to 1022ºF since it would serve for all the exterior surfaces to be tested: barrel, flues, benches and exit. I'd like to have the top one in order to know the flame path temps, but... think knowing how the rest goes would suffice for now.

Thought I haven't still done my first one yet, I'm sure I'll be involved in RMH building around (at least 3 friends waiting for me to finish my own and then help them, and number of interested people nearby growing each day). That's something I want to learn and share... and I think being able to know temperatures along the system will help me to improve my works.
