Device for packaging and applying a substance, the device including a receptacle for containing the substance, an applicator member, and a wiper member secured to the receptacle to wipe the applicator member as the applicator member leaves the receptacle. The signal transmitter includes a hybrid signal device to hybridize the audio signal with the control signal to form a consolidating signal, a frequency modulator to high-frequency modulate the consolidating signal, wherein the consolidating signal is amplified and sent to the signal receiver in a wireless manner. The sacrificial anode material of the anode member is directly in contact with the covering material by being buried or inserted as a tight fit into a drilled hole so that any expansion forces therefrom would be applied to the concrete with the potential of causing cracking. The polishing unit 9 includes a plurality of abrasive clothpaper sheets 7 pressingly held by an inner metal fitting 8, and forms peripheral edges of the abrasive clothpaper sheets 7 into a serpentine shape. The plurality of primary strut first ends are attached together along the longitudinal axis. The entire system may be automated such that each sample in the sample tray may be sequentially analyzed.
