Re: Undergravel heating

Hello again,

When I asked for ways to put probes underwater to measure temperatures I was misunderstood.  
What I meant was that I have used NTC Thermistors (temperature
varient resistors).  My problem is how to seal them so that they 
are waterproof.  I have used heat-shrink, but I can't really
seal the very end of them.

George, I was going to use the LM34, but we decided that the Thermistors 
were cheaper and actually more accurate (depending on which you get).
