A sensor including first and second electrodes can be used to determine the concentration of at least one chemical constituent in a fluid sample under test. The electrodes can be disposed in the fluid sample and a predetermined voltage can be applied to a first electrode. The voltage can cause a current to flow between the first and second electrodes through the sample, the current dependent on the concentration of the chemical constituent in the fluid sample. A sense resistor is coupled to the first electrode such that the current flowing between the electrodes flows through the sense resistor. A processor electrically isolated from the electrodes can receive data signals indicative of the voltage drop across the sense resistor and the voltage applied at the first electrode. The received signals can be used to determine the concentration of the constituent in the fluid sample.

Certain embodiments include a sensor system for measuring chlorine concentration in water. The sensor system can have a manifold including one or more flow passages for receiving fluid flow. The sensor system can have a probe for measuring chlorine concentration in fluid communication with a flow passage of the one or more flow passages of the manifold. The probe can have a probe body oriented to direct incoming fluid from one or more flow passages of the manifold toward an end of the probe body. The probe can have a plurality of flutes defined on an outer surface of the probe body. The flutes can be shaped and oriented to direct fluid from the end proximal to the electrodes, back toward the one or more flow passages of the manifold.

Sensor system and method for sensing chlorine concentration

A sanitizer generation system supplies power to a first and a second sanitizer generator. Each of the sanitizer generators is connected to a body of water by a circulation system. The system includes a power supply and a control system connected to the power supply and the sanitizer generators. The control system selectively delivers electric current from the power supply to the first and second sanitizer generators.

Dual generator single power source for tandem pool and spa

A device and method for sanitizing and deodorizing including the selective transportation of a sanitizing composition by the capillary action of a wick to an acidic composition which may be held in a reservoir, or which also may be selectively transported through the capillary action of a wick to the reservoir.

Deodorizing and sanitizing employing a wicking device

An automated system of the present invention adds electrolyte into a pool. The automated system includes a sanitizer generator, a circulation system, and an electrolytic solution delivery system. The circulation system, which includes the sanitizer generator, has a suction line and a discharge line that delivers water from the pool through a circulation path. The delivery system controls the introduction of electrolyte into the water.

Automated electrolyte addition for salt water pools, spas, and water features

A device and method for cleaning and deodorizing a unit having an enclosed space not otherwise easily accessible for cleaning and deodorizing.

Device for holding a container for a composition that produces an antimicrobially active gas

A method of producing chlorine dioxide gas in an enclosed space including the steps of electrochemically generating chlorine dioxide gas in an electrochemical cell and transporting the chlorine dioxide gas to the enclosed space.
