Works in great shape, see photos for temperature readings. Tested it and it heats up very quickly. Heats to 1100 C, its highest setpoint. Our thermocouple showed 1059 C (see photos) when we independently verified the reading on the furnace itself, but also our gauge was only a couple of inches into the furnace, not in the center. This furnace is in good working order. Runs on regular 110 V household power.
Our test thermocouple is not included in purchase: only the furnace is included in purchase. No tubes are included in purchase.
