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.

surface, 63" from the floor, in a free-standing environment) |
| 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.
