Patent ID: 7542855

Claim:
A method for using water measuring probes of a water sensing device to measure predetermined characteristics of water proximate to said probes, said method comprising: providing a water-sealed sampling chamber enclosing said probes from said water proximate to said water sensing device, said sampling chamber being constructed to be submerged in a body of water of which said predetermined characteristics of water are to be measured; providing an air vent from an upper portion of said sampling chamber to outside air above said body of water for enabling a flow of air between said sampling chamber and said outside air above said body of water; providing an evacuation device for selectively evacuating water out of said sampling chamber to a location away from said sampling chamber such that water evacuated from said sampling chamber does not perturb water proximate to and outside of said sampling chamber; and controlling an amount of water in said sampling chamber whereby water is only in contact with said probes when said probes are measuring said predetermined characteristics of water in said sampling chamber.
