Abstract
Abstract A device for sensing electrochemical conditions in a fluid media which permits the sensing electrodes to be selectively exposed to or protected from the fluid media. The device is equipped with means to deliver accessory agents such as cleaning solutions, buffering solutions and cleaning water and a cup assembly is provided at the end of the probe to seal off the electrodes from the surrounding media so that the electrodes can be cleaned and calibrated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
48 words
The device as defined in claim 1 wherein said means to expose said electrode and to enclose said electrode and to prevent further communication with said media is a movable end portion of said probe constructed and arranged to move outwardly away from the ends of said electrode.
Claim 2
Dependent Claim
52 words
The device as defined in claim 2 wherein said means to expose said electrode and to prevent further communication with said media remote from said exposure includes rod members connected at one end to said means to expose said electrode and further includes actuation means at the opposite ends of said rods.
Claim 3
Dependent Claim
43 words
The device as defined in claim 3 further including a reservoir for accessory agents, means to deliver said agents to the exposed ends of said electrode and a housing for said reservoir disposed at the end of said probe opposite said movable portion.
Claim 4
Dependent Claim
41 words
The device as defied in claim 4 further including connection means carried by said housing for connecting a recording means remote from said housing and further including amplifying means connected to said electrode and disposed within said housing of said probe.
Claim 5
Dependent Claim
32 words
The device as defined in claim 2 further including a cup member disposed in said movable end portion constructed and arranged with the concave portion adjacent to the ends of said electrode.
Claim 6
Dependent Claim
24 words
The device as defined in claim 6 further including an outlet in said movable end portion and in communication with the said cup member.
Claim 7
Dependent Claim
21 words
The device as defined in claim 1 further including means to deliver accessory agents to the exposed portions of said electrode.
Claim 8
Dependent Claim
22 words
The device as defined in claim 8 wherein said means to deliver accessory agents is a conduit disposed internally of said probe.
Claim 9
Dependent Claim
35 words
The device as defined in claim 1 wherein said means to expose said electrode and to enclose said electrode and to prevent further communication with said media is a movable end portion of said probe.
