Test Equity 115A Temperature Chamber with Watlow F4T, Temp range -73 to 175C, Chamber 16x12x14

Re: Test Equity 115A Temperature Chamber with Watlow F4T, Temp range -73 to 175C, Chamber 16x12x14 from Equip X

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)

Cool Down Transition Times*

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.
