Temperature Controller

Home

A simple temperature controlled enclosure for module testing is shown on the right with the door open.

So far I have managed to achieve a stable temperature of +59C with the existing 50W heater.

Since this photo was taken a layer of insulation and the freezer block tray have been installed. The box now heats up about twice as fast and reaches 40C from room temperature in about 30 minutes.

The compartment holding the control electronics on the right hand side is isolated from the circulating air and ventilated to the outside air.

A clear plastic cover protects the user from contact with the heater and over-temperature cutout in the compartment to the left of the front panel.
