Rate Of Change
To calculate rate of change for a particular condition, take the difference
between the Start Temp and End Temp and divide by the Transition
Time.
Cool Down Example: From +85°C to -40°C = 125°C / 45
min = 2.78°C/min. |
| *Note: Transition times are measured after a 1 hour
soak at the respective start temperature with an empty chamber, as indicated
on the temperature controller, 23°C ambient. |

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.
Due to continuous product development, specifications are subject to
change without notice. |
