A method and system for the wireless interrogation of a body immersed in a circulatory bath or a tank for heating. More specifically, the system may include a probe having multiple sensors for gauging a core temperature associated with the immersed body in combination with one or more wireless connections leading to a controller (on a circulator or a user interface) such that the user can determine temperature information (e.g., core temperature) of the body being immersed.

Method and assembly for a wireless probe and interrogator

An automatic and dynamic filter window for the air inlet to a chiller or cooler is disclosed, including a controller and a scrolling filter for replacing filters prior to clogging or contamination that may compromise the operation of the chiller.

Refrigeration chiller or cooler system with self-cleaning filter

A chiller or cooler is disclosed, including a self-test mechanism to simulate a sampling of normal operations and to compare the operating parameters resulting from such sampling against factory operational parameters adjusted for differences in operating parameters so as to eliminate unnecessary servicing or maintenance events.

Self-test system for qualifying refrigeration chiller system performance

A constant temperature circulator assembly may include a circulator head assembly having a fixed display and a base ring assembly adapted for connection to a container wherein the circulator head assembly movably engages the base ring assembly so that an orientation of the fixed display may be selectively adjusted with respect to the base ring assembly.

Movable constant temperature circulator assembly

Constant temperature circulator

An constant temperature circulator for maintaining a liquid at a constant temperature including a housing that encapsulates a controller, a display, a heating element, a temperature sensor, and an electric motor having an impeller. The housing includes a first port and a second port that cooperatively define a chamber that encapsulates the impeller, an aperture and an opening, such that actuation of the impeller when the electric motor is activated by the controller moves the liquid from the aperture, through the chamber and to the opening.
