When selecting your spa or hot tub sensor, it’s critical that you go by part numbers and not just by appearances.  The part number on a sensor can be found on a white or silver label located directly on the senor cable (The ID label may also be located on the casing of the sensor).  Buy based on this part number.  Do NOT purchase a hot tub sensor just because it looks the same as the one you’re replacing.  Spa and hot tub sensors can look identical, but have different resistant and material to work with different spa and hot tub controllers or circuit boards.  ALSO pay attention to the type of cable plug that is on the end of the sensor cable.  Different spa and hot tub sensors use a certain type of cable plug that plugs into compatible spa and hot tub controllers or circuit boards.
