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, 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. Performance is reduced by 17% with 50 Hz input power.

| Instrumentation | ||
| Temperature Controller | Watlow F4T Touch Screen Controller with RS-232, Ethernet interface, 4.3" color graphic touch screen. OR... Watlow F4 Controller with RS-232 interface, LED readout of temperature, LCD display of other parameters. | |
| 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 Power Requirements | |||
| Phase | Current Draw | Minimum Service | |
| 230 V ±10%, 60 Hz | 1 PH | 25 A | 30 A |
| 3 PH | 19 A | 25 A | |
| 208 V -5/+10%, 60 Hz | 1 PH | 28 A | 35 A |
| 3 PH | 21 A | 30 A | |
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. Performance is reduced by 17% with 50 Hz input power.
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.
