Review on Honeywell 394530 Thermocouple Tester Assembly by Joel Miranda

WHAT?! ONLY FOR THIS?! Yes, but what a time saver. Just don't lose. As a tester for a gas water heater thermocouple, press it, press the button, it should hold for at least 30 seconds (if you have a flame at the end of the thermocouple so the button is held), if not, replace it the thermocouple. Quick and easy and the first thing you check (and usually the first thing to wear out) when fixing a water heater when it's not leaking (duh). There are cheaper options but I know for sure it always works but I don't want to gas guess.
