Product Description
The Yamato DH-612 is a 216 L high performance programmable fine oven. “Fine oven” is Yamato’s designation for its tightest-controlled line, and the number that earns it is a temperature adjustment accuracy of ±0.2 °C (at 360 °C).
The DH models are the high temperature version of the same cabinet — identical construction and controller, with more heater capacity and a higher ceiling. Everything else about the machine is the same, so the choice between DF and DH is purely about the temperature your process needs.
