I am looking at buying a digital pyrometer for my lp gas forge. The plan is to have the pyrometer so that I can regulate the temp for quenching the blade. The question at hand is how high of a temp range would you suggest for the pyrometer. I can buy one that goes up to 2000 F for about seventy bucks on EBAY. Or pay a little more for one that goes up to 2300 F. Should I spend the extra money on the 2300 F. Just need someone else to pipe in.:cool:
 
Get a "K" type thermocouple.

Also, a PID is probably cheaper and does the same thing as a pyrometer plus a whole bunch more if you ever want to switch to automatically controlled forge.
 
What about the power source such as nine volt battery or 120 v ac blah blah blah. The pyrometer I am looking at is battery operated and has a 4 inch long thermocoupler on a 3 foot lead. Are you using a PID. By the way I found some PID's on EBAY but they don't come with 4inch long thermocoupler probe.
 
I am using a PID but only to read the temps.

That unit I posted the link to is 110 volt but they have 12/24 V ones as well.
 
I've been fortunate enough to get some questions of mine answered by Stacy Apelt and he recommended these links to me to help in understanding the PID controlled forge. There is also some discussion of Pyrometer and PID's just for reading temp. without controlling the forge so they will be of interest to you. Personally even if your not interested in going the PID controlled route at this time it would be a worthy investment to get a 2300 degree PID to read your temp so it would be easily upgradable in the future if you wanted.

Just my opinion here, and I have yet to start building anything and have no experience in these matters so take it for what it's worth from one person learning about PID to another.

Hope this helps - Josh
