Test Equity 115 Temperature Chamber  (Environmental Chamber).Digital programmable controller with limit controller.

Temperature Range
-73°C to +175°C
Control Tolerance
±0.2°C (Measured at the control sensor after stabilization)
Uniformity
±0.5°C (Variations throughout the chamber after stabilization)
Heat Up Transition Time*
5°C/minute typical
Cool Down Transition Time*
Start Temp End Temp
+23°C 0°C -40°C -55°C -65°C -73°C
+23°C ----- 5 min 20 min 30 min 40 min Ultimate
+85°C 16 min 25 min 45 min 57 min 69 min Ultimate

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.
