Artesian Spas Temperature Sensor OP80-0052-08

Factory original Artesian Spa heater sensor OP80-0052-08. 2 pin female connector plugs right into 2 pins on circuit board.

This is a 12 inch long sensor that works in Artesian spa heaters where the sensors are installed inside the heater. 

Does not come with the mounting nut which should already be part of your existing assembly.  This is the factory original replacement sensor.  (sensor less the Heyco cap, oring and washer - not included)

There are 2 sensors built into the heater. It is recommended to change out both sensors at the same time as they work in conjunction with each other and the system board.  These work interchangeably as temperature and hi limit sensors within the heater.

This is the original part as supplied by Artesian Spas.
