  • Fluid content monitor
    Patent number: 8119068
    Abstract: A fluid content monitor including a cuvette, a colorimeter adapted to generate a signal indicative of contents of a fluid sample contained in the cuvette, a container for holding a reagent, and a pump assembly for delivering reagent from the container to the cuvette. The pump assembly includes a tube extending from the container to the cuvette, check valves preventing reverse flow in the tube, and a hammer driven by a solenoid for repetitively compressing the tube to pump reagent to the cuvette. The cuvette can be removed for cleaning and replacement.
    Type: Grant

  • Turbidimeter with ultrasonically cleaned components
    Patent number: 7808642
    Abstract: An ultrasonic optical cleaning system is provided for cleaning and deterring the buildup of organic and inorganic particulates from the surface of glassware used in water testing instrumentation. The ultrasonic optical cleaning system includes a transducer that is attached to the surface of the glassware. A connector cap carrying a plurality of spring contacts interconnecting the transducer with an ultrasonic transducer control circuit. The control circuit operates continuously to provide an electrical signal to the transducer that vibrates the transducer and the glassware so that the glassware is cleaned of contaminates.
