Product Description
Safety Devices
Fisher Scientific Peltier Low Temp. Incubators 4-7
Safety Devices
The low temperature incubators are equipped with the following safety features:
• a sample protection feature that safeguards the samples against destruction through
overheating in case of controller failure;
• an overheat protection cut-out feature class 2 (TWB), according to DIN 12880, that shuts
down the low temperature incubators IMP completely when excessive temperatures occur
in the workspace;
• an alarm relay that is energized, along with audible and visual alarms, to indicate errors
encountered during operation;
• dual fuses rated at 15 amperes.
Work Space Atmosphere
To ensure undisturbed operation, the ambient temperature in the operating room must be at
least 18 °C (64.4 °F).
The heating system uses this temperature threshold to control the ambient temperature plus
10 °C (50 °F) up to the maximum of 60 °C (140 °F).
Sensing and Control System
The PT 100-type sensor for the control of the work space temperature and for the thermal
protection is installed on the bottom of table-top low temperature incubators and in the top of
floor stand low temperature incubators.
