I think I understand the difference between a thermocouple and a probe, but I want to be sure I am picking the right thing.
I am building an electric HLT that will be controlled with a PID.
I am buying the Weldless Thermometer Sight gauge from Bargain Fittings seen here:
I think I need a probe with a 1/2" NPT back thread. I need to find something like this, but with 1/2" instead of 1/4" (and hopefully a little cheaper)
From what I understand, a thermocouple will not work because it will stop the liquid from filling in the site guage.
I'm sure other people have bought the same sight gauge from bargain fittings, what are other people using?
