±0.2°C (Measured at the control sensor after stabilization)
±0.5°C (Variations throughout the chamber after stabilization)
Heat Up Transition Time*
Cool Down Transition Time*
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 = 2.78°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.
