This Digital Heat Pad is suitable for use with out Vacuum Chamber and Extraction Systems. The Heat Pad attaches to the bottom of your chamber with a peel back adhesive.
The digital heater is super accurate, and will hold a temperature to within a degree (depending on the environment and air movement).
The controller has a temperature offset that will need to be found to set the controller accurately. Anything you attach a heat pad to will act like a heat sink, so the set temperature will be different from the actual inside temperature.
