Thermcraft 25-36-5ZH 5-Zone Tube Furnace 240VAC, 1Ph, 50A, 11965W, 1200C

This Thermcraft 25-36-5ZH 5-Zone Tube Furnace (240VAC, 1Ph, 50A, 11965W, Max. Temp. 1200°C) with 501-50-240 Controller looks to be in good cosmetic condition, showing some signs of wear.

It powers up, and I was able to adjust the set point on each of the controllers, and the furnace heats up, as shown.

I set all five temperature controller to the maximum of 1200°C, but the chamber only heated up to the 500~700°C range, as shown. I'm not sure how to adjust the limit controller, so that might have something to do with it.

This is the extent of my testing of this furnace, and it is being sold as-is.

The tube furnace is about 42 inches long overall, but the heated section appears to be 36 inches in length.

It has an inner diameter of about 5 inches.

Approximate overall unpacked dimensions: 50"L x 36"W x 44"H.
