Isotemp Standard Incubators 1-1Fisher Scientific
Section 1 Introduction
Fisher Isotemp 600 Series Standard incubators are available in three sizes:
Small, Medium and Large. All incubators provide PID microprocessor
control at operating temperatures ranging from 30 (86°F) to 75°C (167°F).
Note Ambient temperature must be at least 5°C below operating
temperatures. s
In these incubators, fresh air enters through an air intake on the bottom of
the incubator, then is heated in a plenum below the chamber, finally
flowing into the incubator chamber itself in uniform flow patterns.
Exhaust air is vented through a port at the top of the incubator.
Temperature readouts and control parameters are shown in red LEDʼs.
Three additional LEDʼs indicate when the heater power is being applied,
an error condition is encountered, or the temperature is being set.
The Small incubator accommodates a maximum of three shelves. The
Medium incubator holds six shelves, and the Large incubator holds 10
shelves.
Isotemp incubators incorporate a variety of safety features. A safety backup
is built into the controller software. If the primary heater control fails, the
backup will maintain control at 3°C above the set point. An alarm LED
then indicates that the backup controller is operating the incubator. A
circuit breaker protects the incubator from power surges.
