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 (empty): From +85°C to -20°C = 105°C
/ 17 min = 6.18°C/min.
Heat Up Example: From -40°C to +85°C = 125°C / 11
min = 11.36°C/min.
*Note: Transition times are measured after a 30 minute soak
at the respective start temperature. |

| 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 will result
in decreased cooling performance. Low end limit derates to -38°C when
operating above 27°C (80°F) ambient. Operation above 30°C (85°F)
or below 16°C (60°F) ambient is not recommended. |
