I built several probes for measuring the temperature of hot water. They are
made of copper refrigeration tube, closed at one end by sawing a cross in
it, folding over, and soldering. I wired up a sensor to some telephone
cable and stuck it into the tube with some heat sink gunk, then closed the
whole thing with some special heatshrink tubing that has an internal layer
that melts to make a great seal. Very successful probes but a fairly high
thermal mass. The copper tube goes into a fitting made out of a compression
union cut in half with the brass compression ring replaced with an o-ring.
Works very well - couldn't be better, in fact.
I made some cold water probes just by putting the same heatshrink right over
the wire and sensor, leaving the sensor package sticking out a bit. Also
very successful and much less thermal mass.
