Heat treat oven or Kiln?

[mksj]

There are a number of manufactures that make small ovens/kilns for jewellery, knife making and heat treatment that are relatively light, they heat up quickly, and they have a number of programmable features. It will hold very tight temperatures and some have features to flow inert gas in the heating chamber. I use a small Paragon oven, but the interior size is a bit small. The knife making ones tend to be a bit longer. Prices can vary quite a bit but I have seen ones with a PID control starting around $600. Pottery kilns tend to be much heavier, are slow to reach temperature and can be hard to keep the temperature in a narrow range.
