Q: Is it waterproof?

Задавает Tim Wertinger на 2017-11-07 03:41:59

FediaB For 3-4 months maybe waterproof ... See: Confirmed!. The THIRD my unit used to work for about 4 months (installed end of August, stopped end of December), after what now shows random temperature between 50 and 75 degrees, instead of 36-39. I disassembled 2nd unit to see what is wrong and found that some water entered PCB compartment and made some deposits on the solder side. What I mentioned is, that the PCB itself is not covered by say, epoxy paint or maybe some "contemporary" coating was used, than does not protect the board at all. After cleaning and resoldering this board shows right temperature, but just blowing on the pcb set it in "wrong temperature" mode until power off/on
