Abstract: The present embodiments include assemblies and methods for releasably sealing a dipstick tube with a piston valve assembly in a sealable engine fluid measurement probe assembly. In an embodiment, the piston valve assembly is integrated in a handle portion of the sealable engine fluid measurement probe assembly. The seal may be established with an o-ring positioned on an outer diameter of a portion of the sealable engine fluid measurement probe assembly that is configured to be inserted into the dipstick tube. A port or opening on either side of the o-ring is coupled to the piston valve, or other equivalent valve assembly, for allowing air or other gases to bypass the o-ring, thereby releasing the seal between the sealable engine fluid measurement probe assembly and the dipstick tube.

Abstract: A method and apparatus for increasing the efficiency of an air conditioning system. Misting the air conditioning system's condenser with water cools the condenser and enables the system to more rapidly condense the refrigerant therein. By increasing the rate at which the refrigerant is condensed, energy and wear and tear on the system is reduced. Control of the misting is important, and sensing environmental and other present metrics to assist that control increases the efficiency offered by the present method and apparatus.
