    摘要： A two component dental composition is disclosed which eliminates or substantially reduces the discomfort and pain associated with dentinal hypersensitivity which composition comprises a first dentifrice component having an alkaline pH, a second dentifrice component having an acid pH and at least one of the components containing a potassium ion releasable compound, the first and second components being maintained separate from each other until dispensed and combined for application to teeth requiring relief from dentine hypersensitivity, whereby heightened desensitization is experienced by the user.

    摘要： A multimeter having an elongated housing with a fixed recess for receiving a current-carrying conductor is provided. The multimeter is adapted to measure various parameters including a.c. and d.c. voltage, resistance, and a.c. current. On one end of the elongated housing of the multimeter is a C-shaped current sensor mounted around the fixed recess for measuring a.c. current in the current-carrying conductor and on the other end is a pair of test leads for measuring resistance, a.c. voltage, and d.c. voltage. The current sensor and the test leads provide input signals to an analog-to-digital converter (ADC) to obtain digital samples which are displayed as measurement results according to the selected measurement mode.
