Model 123HS Temperature/Humidity Chamber - Specifications
Standard Range: 10% to 95%
(Limited by a 6°C dewpoint and maximum dry bulb of +85°C)
With GN2 Purge or optional 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
*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 on 123HS-EX 50 Hz export versions by 17%.

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.
