Additional Info

Temporarily out of 3 and 3.5" HeatPads.  Please consider alternative semi-finished modules listed in http://www.mhi-inc.com/PG4/thermoplate-hot-plate.html.

Monitor Heatpad surface temperature so that surface temperature measured by a pyrometer (set with ceramic emissivity) does not exceed rated temperature of HeatPad.  Rated temperature is given in installation manual.  The current draw may be far lesser than the max amps when not in free radiating condition of use.

Available Options:
     

Thermal shock resistant, high density NanoFractalAlumina™ translucent setter plates and crucibles (sold separately).  For Alumina boats and crucibles visit www.buyrefractory.com.  Placing a NanoFractalAlumina™ object or other objects on the Heatpad™ will generally reduce the current input required to obtain a particular surface temperature of the HeatPad™.   Excees current input can burn out the HeatPad™.  Please use feedback controls if available or monitor surface temperature of the Heatpad™ to ensure that the maximum temperature is not exceeded.
