Disclosed is a magenta toner, which contains magenta colorants composed of compound A represented by Formulas, or in an amount of mA and compound B selected from a group consisting of a mono-azo pigment, a naphthol pigment and rhodamine chelate pigment in an amount of mA, and a ratio of amount mA:mB is 90:10 to 55:45. A first analog to digital converter is arranged for converting an analog output voltage of the switched-mode power supply into a digital output voltage, means are arranged for transforming the digital output voltage into a digital current threshold level and a digital to analog converter is arranged for generating the analog current threshold level according to the digital current threshold level. A television set located remotely from the antenna receives the television program stream via the network and displays the program. Preferably, the housing is generally C-shaped with the test strip spanning the space between the two arms of the C-shape. Through dry storage and simple dissolution, even in a home, the invention enables a wider variety of solution constituents, including reduced acid content and the use of bicarbonate as a stable buffer component. The devices of the present invention take advantage of combinations of pumping conduits and conducting conduits to permit the use of lower operating voltages in pumps, pressure multipliers, and flow controllers.
