Test Equity 115A Temperature Chamber with Watlow F4T

• 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)

• Heat Up Rate of Change*

5°C/minute typical

• Cool Down Rate of Change*

2.8°C/minute from +85°C to -40°C (standard 60 Hz models)

2.1°C/minute from +85°C to -40°C (115A-EX 50 Hz export models)

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 +85°C to -40°C = 125°C / 45 min = 2.8°C/min.
• *Note: Transition times are measured after a 1 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. Measured at nominal line voltage of 120V, 60 Hz. Performance is reduced on 115A-EX 50 Hz export versions.

• 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 development, specifications are subject to change without notice.
