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 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.
