Vintage Thermolyne Pyrometer & Millivoltmeter, Model PM-1K35 - Serial Number 432971.
Analog meter measures up from 0 F/C to 1600 degrees F., or 870 Degrees C. It also reads out in millivolts - from 0 mv to 37 mv. A thermometer on the side reads from 0 C/30 F to 40 C/100 F. Comes in case with hinged lid & handle.
Instructions are inside the lid of the case. The case and unit visually appear to be in excellent condition - unit has not been tested because there are no leads with it (they are available at Radio Shack or other Electronic Supply stores).
