Constant temperature circulator

Abstract

An constant temperature circulator (100) for maintaining a liquid at a constant temperature including a housing (104) that encapsulates a controller (114), a display (116), a heating element (118), a temperature sensor (120), and an electric motor (122) having an impeller (126). The housing includes a first port (132) and a second port (134) that cooperatively define a chamber (136) that encapsulates the impeller, an aperture (142) and an opening (150), such that actuation of the impeller when the electric motor is activated by the controller moves the liquid from the aperture (142), through the chamber (126) and to the opening (150).

CLAIM 
     
       The ornamental design for a constant temperature circulator, as shown and described herein.
