It will give you an ohm reading, compare it to that chart. Do the same test with hot water(dont burn yourself), again compare the reading with the chart. If the sensor reads close enough, thats the one you want to use. Plumber by trade, i can tell you that the threads on those sensors are tapered, meaning that as long as the threads are correctly made, you wont need a sealent to make it seal. Tighten hard(better seal, better ground connection), if it leaks tighten some more.

Has anyone done this with the chart and mapped them?
