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 +50°C to -40°C = 90°C / 27
min = 3.33°C/min.
Heat Up Example: From -40°C to +50°C = 90°C / 11 min
= 8.18°C/min.
*Note: Transition times are measured after a 2 hour soak at
the respective start temperature with an empty chamber. |

| 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 single or three
phase in the field by changing jumpers. Three phase load is semi-balanced.
Call for 50 Hz operation. Cooling performance is reduced 17% at 50 Hz.
Customer power source must be hard-wired to the chamber by a qualified
electrician. Power cord and plug is not included. |

| Weight |
Chamber Weight: 850 pounds
Shipping Weight: 1,013 pounds |
| Sound Level |
62 dBA in cooling mode (A-weighted, measured 36" from
the front or side 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 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. |
