March 5, 20179 yr Hi all Recently picked this up at a car boot sale for £1. An American made Bacharach thermometer for testing combustion efficiency of boilers/furnaces. Accurate temp range between 200 and 1000f which is between around 93 and 537 deg Celsius. The steel hollow open ended sensor pipe on the back is 5 1/2" long. I think I have a couple of uses for it but would like to hear from members as to usefulness.

I do have a redundant deep oil fryer for smaller parts, its around 12" x 6" x 5" with a good working element that tops out at 190c on a thermostat. The other is an 'oil bath' 24" x 12" x 8" steel box with lid but I haven't a way yet to heat the oil I may put in it.
March 6, 20179 yr I put one in my forge exhaust pipe to make sure the temperature did not go so high that the zink started burning. I removed it when I found that the temperatures were so far below that monitoring was meaningless. Besides we now have cheap IR-thermometers. I might put it in an old kitchen oven without thermostate that I someday will turn into annealing.
March 6, 20179 yr Author Thanks gote, excellent idea. My wife is just getting into pottery and will be soon given and old electric kiln. Sounds like it may have found its home(now and again!)
