Model 1016H-2 Temperature/Humidity Chamber Specifications


Temperature Range
-73°C to +175°C
Control Tolerance
±0.5°C (±0.2°C Typical) (Short-term variations measured at the control sensor after stabilization)
Uniformity
±1.0°C (Variations throughout the chamber after stabilization)
Humidity Range
Standard Range: 10% to 95% (Limited by a 6°C dew point 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)

Temp/Humidity Range

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.

Control Tolerance
±3% RH max., ±1% RH typical at 85% RH (Short-term variations measured at the control sensor after stabilization)
Display Resolution
0.1% RH
Humidity Sensor
Dynamic capacitive type (no wet wicks required)

Heat Up Transition Time (empty, uncontrolled humidity mode)*
-40°C to +85 °C @ 208V input 28 minutes (4.5°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 end temperatures with an instantaneous step change in Set Point without a controlled ramp-rate. Does not include the effect of proportional band when approaching setpoint. Performance is reduced by 17% with 50Hz input power.

Instrumentation
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
Phase Maximum Current Draw Minimum Service
230 V ±10%, 60 Hz 1 PH 36 A 45 A
3 PH 24 A 30 A
208 V -5/+10%, 60 Hz 1 PH 33 A 45 A
3 PH 22 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.

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.
