(Requires NT-TEMP)

The NT-H2O water temperature sensor is designed to work in conjunction with the NT-TEMP sensor of the UP32 thermostat family.  The NT-H2O is a waterproof probe  with an integrated o-ring for direct insertion into the water stream (1/4" dia hole size) connected to a 6' lead.  This allows the associated NT-TEMP electronics to be mounting indoors.
