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 -40°C = 125°C
/ 28 min = 4.5 °C/min.
Cool Down Example (with 80 lb. load): From +85°C to -40°C
= 125°C / 48 min = 2.6°C/min.
Heat Up Example (empty): From -40°C to +85°C = 125°C
/ 17 min = 7.35°C/min.
Heat Up Example (with 80 lb. load): From -40°C to +85°C
= 125°C / 29 min = 4.3°C/min.
*Note: Transition times are measured after a 2 hour soak at
the respective start temperature at 208 V input. |

| 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. |

Input may be configured for 230 V or 208
V in the field by changing jumpers. Three phase load is balanced. 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 is 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.
Due to continuous product improvements, specifications subject to change
without notice. |
