Abstract: A system for dispensing a detergent solution from a solid detergent into a dishwasher includes a dispenser that can collect water sprayed into the dishwasher and use the collected water to produce the detergent solution by dissolving a portion of the solid detergent, controlling the amount of the detergent solution produced, and releasing the produced detergent solution between cleaning cycles. The dispenser can perform these functions automatically without being electrically powered.

Abstract: 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.

Abstract: Embodiments provide a handheld fluorometer and method of determining a concentration of a product within a sample. In some cases the handheld fluorometer includes an immersible sensor head that measures a fluorescence of the product and a controller that calculates the concentration of product. In some cases the handheld fluorometer includes a handheld controller module, an immersible sensor head connected to the controller module, a sample cup for containing a water sample, and a fastener that removably fastens the sample cup about the immersible sensor head. In some cases the sensor head is angled with respect to the controller module and the fluorometer provides a substantially stable base. The sample cup can be removed to acquire a sample of water containing the product and then refastened about the sensor head for determining the concentration.
