An improved method of attachment of a pH or p sensor in the recirculation/filtration line for a pool or spa or for forming a T-connection between any two pipes comprises a saddle-clamp modified with an aperture to receive the shank of the sensor with an O-ring and a thinner, harder constricting ring

An improved method of attachment of a pH or p sensor in the recirculation/filtration line for a pool or spa or for forming a T-connection between any two pipes comprises a saddle-clamp modified with an aperture to receive the shank of the sensor with an O-ring and a thinner, harder constricting ring surrounding the O-ring. When the saddle clamp is tightened, the constricting ring forces the O-ring toward the aperture while preventing excessive flattening of the O-ring.

A water analysis system for continuously analyzing the water in a recirculating line for pool, spa or the like, comprising in combination: a set of adjacent sensors for mounting in said line said sensors including: a cylindrical shaft surrounding each of said sensors; a first oxidation-reduction pot

A water analysis system for continuously analyzing the water in a recirculating line for pool, spa or the like, comprising in combination: a set of adjacent sensors for mounting in said line said sensors including: a cylindrical shaft surrounding each of said sensors; a first oxidation-reduction potential (ORP) sensor mounted on the wall of the line with a sensing probe dispersed in the water in the line for developing a first electrical signal at its output directly related to the active concentration of the form of an oxidation sanitizer contained in the water; a second pH sensor mounted on the wall of the line with a sensing probe dispersed in the water in the line for developing a second electrical signal at its output directly related to the acidity/basicity level of the water in the line; means for mounting each of the probes on the wall of the line including an aperture through said wall for receiving the shaft, an assembly of an inner O-ring and an outer constricting ring slidably mounted on the shaft, said constricting ring being harder than the O-ring and having a height smaller than the diameter of the O-ring slidingly positioned on the outside edge of the O-ring and a belt clamp having an aperture receiving the shaft of the sensor and having a belt surrounding the line and means for tightening the belt clamp whereby the clamp flattens the O-ring between the belt and the wall of the line while it is constrained by the outer constraining ring; an analyzer unit having a housing covered by a face plate and including: a first bargraph display having a visual indicator movable over a first range corresponding to concentrations of sanitizer below and above optimum concentration mounted on said face plate; a first sanitizer scale having a height equal to said first range printed on the face plate adjacent the first bargraph display indicating in the below optimum portion of the range a printed instruction to add sanitizer; a second bargraph display having a visual indicator movable over a second range corresponding to pH mounted on said face plate; a second scale printed on the face plate adjacent the second bargraph having a height equal to the second range including printed instruction in the high pH range to add acid and a printed instruction in the low pH range to add base; a compartment within said housing for receiving a battery; first electrical driver means electrically connected to said battery compartment and operably connected between the output of said first sensor and the first bargraph display for moving the first bargraph display in step increments over the first range; and second electrical driver means electrically connected to said battery compartment and operably connected between the output of the second sensor and the second bargraph display moving the second bargraph display in step increments over the second range.
