Model 107 Benchtop Temperature Chamber Specifications

Temperature Range

-42°C to +130°C

Control Tolerance

±0.5°C (±0.2°C Typical) (Short-term variations measured at the control sensor after stabilization)

Uniformity

±1.0°C (Variations throughout the chamber after stabilization)

Heat Up Transition Time (empty)

8.5°C/minute typical

Cool Down Transition Time (empty)*
Start Temp		End Temp
Start Temp		+23°C	0°C	-10°C	-20°C	-30°C	-35°C	-40°C	-42°C
+23°C	Standard	----	7 min	11 min	15 min	19 min	23 min	30 min	Ultimate
+23°C	50 Hz Export Version	----	8 min	13 min	18 min	23 min	28 min	36 min	Ultimate

+85°C	Standard	13 min	20 min	24 min	28 min	32 min	36 min	45 min	Ultimate
+85°C	50 Hz Export Version	16 min	24 min	29 min	33 min	38 min	43 min	54 min	Ultimate

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 / 28 min = 3.75°C/min.

*Note: Transition times are measured after a 30 minute soak at the respective start temperature with an empty chamber, as indicated on the temperature controller, 23°C ambient. Measured with setpoint beyond the start and end temperatures. 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 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.

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