Economically-priced, space-saving, yet high-capacity constant temperature ovens for educational facilities and small
laboratories.
It is a forced convection, circulatory type of oven that disperses heat with high
precision.
- Temperature adjustment is achieved through proportional, integral, derivative
(PID) control using a microprocessor, and boasts auto-starting, auto-stopping,
and timer features.
- When shipped from the factory, the door opens to the left, but the user can
manually change it so it opens from the right.
- The unit has several safety features, such as a short circuit breaker, and an
independent mechanism to prevent overheating that uses a thermostat with
digital switches.
