Re: Undergravel heating
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).
