Reference No.: 281LC
Description: TestEquity Model 1007H Temperature/Humidity Chamber
Standard Range: 10% to 95%
(Limited by a 6°C dewpoint and maximum dry bulb of +85°C)
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.

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.

|Compressors||1.5 HP x 1.5 HP Tecumseh hermetic compressors in a cascade configuration.|
|Heat of Rejection||14,800 BTUH (maximum rated chamber load at maximum cooling rate from high temperature soak)|
|Air Heater Power||2,000 Watts|
|Humidifier Heater Power||1,500 Watts (rating at 240V)|
|Air Flow||450 cfm|
|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 other voltages or 50 Hz operation. Performance is reduced by 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.
|Humidity Water Requirements|
|Supply and Drain||Must be provided with a water line and floor drain. Negligible consumption.|
|Water Recirculation System (optional)||Provides a reliable supply of filtered water for the humidity system. Perfect for installations where a water line and drain are not available.|

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.
