-35°C 5.5 min 10 min 16 min 23 min 29 min 34 min

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 -10°C = 95°C / 14 min = 6.8°C/min.
Cool Down Example (with 25 lb. load): From +85°C to -10°C = 95°C / 22 min = 4.3°C/min.
Heat Up Example: From -35°C to +85°C = 120°C / 16 min = 7.5°C/min.

*Note: Transition times are measured after a 2 hour soak at the respective start temperature.

Temperature Controller Panel
Limit Controller Independent high and low temperature limits. Triggers an audible alarm and shuts down the chamber. Relay contacts provide a safety power interlock for test sample.
Chart Recorder (Optional) Honeywell DR4300 Series. One pen, 10" circular chart. Mounts in lower front door. Honeywell Chart Recorder

Input Power Requirements
230 V ±10%,
60 Hz, 1 PH		 Max Current Draw 22 A; Recommended Service 30 A
208 V -5/+10%,
60 Hz, 1 PH		 Max Current Draw 22 A; Recommended Service 30 A

Input may be configured for 230 V or 208 V in the field by changing jumpers. Single phase input only. Call for other voltages or 50 Hz operation.

Customer power source must be hard-wired to the chamber by a qualified electrician. Power cord and plug are not included.

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.
