±1.0°C (Variations throughout the chamber after stabilization, -40°C to +85°C)

Cool Down Transition Time (empty)*
	End Temperature
	+23°C	0°C	-20°C	-40°C	-55°C	-65°C
Time from +23°C: °C/minute:	__	1 min 23°C/min	5 min 8.6°C/min	10 min 6.3°C/min	15 min 5.2°C/min	20 min 4.4°C/min
Time from +85°C: °C/minute:	7 min 8.9°C/min	12 min 7.1°C/min	17 min 6.2°C/min	23 min 5.4°C/min	29 min 4.8°C/min	35 min 4.3°C/min

Heat Up Transition Time (empty)*
-40°C to +85 °C	15 minutes (8.3°C/minute)
*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 50Hz 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
230 V ±10%, 60 Hz, 3 Phase	Max Current Draw 39 A; Recommended Service 50 A
208 V -5/+10%, 60 Hz, 3 Phase	Max Current Draw 35 A; Recommended Service 45 A
	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 50Hz operation. Performance is reduced by 17% with 50Hz input power. Customer power source must be hard-wired to the chamber by a qualified electrician. Power cord and plug is not included.

Outside Dimensions	38" W x 78.5" H x 56" D (nominal) 914 mm W x 1994 mm H x 1422 mm D Door latch adds 3" to width on right side.
Minimum Installed Clearance	18" from the left and right side 24" from the rear
Window Viewing Area	18" W x 12" H
Access Ports	4" Port on left and right side (two total). Supplied with foam plugs.
Weight	Chamber Weight: 1,130 pounds Shipping Weight: 1,280 pounds
Sound Level	68 dBA in cooling mode (A-weighted, measured 36" from the front 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.

Due to continuous product improvements, specifications subject to change without notice.
