Iíd like to do my own E6 processing but for various reasons I canít get a constant a constant 114F out of the tap. Iíd like to find a submersible water heater that I can use in the water bath. Submersible fish tank heaters will hold +- 1F but only go up to about 93F. Nova Darkroom makes these:
But I canít find a USA version and even if I did an international order voltages are different in the US. I bet there must be something outthere I can use to keep my waterbath at 114 or so.
