*Note:
Transition times are measured after a 2-hour soak at the start temperature with an empty chamber. Does not
include the effect of proportional band when approaching setpoint.

NOTE:
Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. Designed
for use in a normal conditioned laboratory. Operation at higher ambient temperatures may result in decreased
cooling performance. Additional ports and shelves will also affect performance. Operation above 30°C (85°F) or
below 16°C (60°F) ambient is not recommended.
