Abstract: A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

Abstract: A probe for sensing radio frequency power, utilizing two independently-driven radio frequency-sensitive diodes. The two diodes are driven through a common RF input, through a branch network which separates and feeds the probe RF power to each diode independently. The diodes are unequally padded from the RF input, to provide an extended sensitivity range for the probe. One diode, therefore, operates in a lower dBm range, while the other diode operates in a higher dBm range. Two separate outputs are provided from the probe to supply a common power meter which monitors the appropriate output for the present power level of the radio frequency input.
