Introduction
Thermo Scientific Precision 3051 Series Standard ovens are available in
three sizes: Small, Medium and Large. All ovens provide analog, on/off
control at operating temperatures ranging from 50°C (122°F) to 225°C
(437°F).
Inlet air enters through a port located under the oven floor. Heat-
generated convection then gently moves the air in a vertical circulation
pattern. Exhaust air is vented through a port at the oven top.
The Small oven accommodates a maximum of five shelves. The Medium
oven holds eight shelves, while the Large holds up to eleven shelves.
Precision ovens incorporate a variety of safety features. A safety backup is
built into the controller: if the primary heater control fails, the backup will
maintain control at 5°C above the set point. An alarm LED then indicates
that the backup controller is operating the oven. A circuit breaker protects
the oven from power surges.
