Model 1027H Temperature/Humidity Chamber Specifications
With optional GN2 Purge or Dry Air Purge: 5% to 95%
(Dry bulb range of +10°C to +85°C)
NOTE: Ability to reach RH extremes may be limited by the humidity sensor accuracy. Low Dew Point conditions can only be achieved when starting with a clean, dry chamber.
|Cool Down Transition Time (empty, uncontrolled humidity mode)*|
|Time from +23°C:
|Time from +85°C:
|Heat Up Transition Time (empty, uncontrolled humidity mode)*|
|-40°C to +85 °C||25 minutes (5°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.

|Heat of Rejection||27,500 BTUH (maximum rated chamber load at maximum cooling rate from high temperature soak)|
|Heater Power||4,200 Watts @ 208 V input|
|Air Flow||830 cfm|
|Temp/Humidity 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. Two pen, 10" circular chart. Mounts in lower front door.|
|Input Power Requirements|
|230 V ±10%, 60 Hz,
|Max Current Draw 39 A; Recommended Service 50 A|
|208 V -5/+10%, 60 Hz,
|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.

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.
