DEFINITION

Classification: 422/82.01

Measuring electrical property:

(under subclass 68.1) Apparatus having means for measuring an electrical property such as detecting the presence of electrical charge carrying substances (e.g., ions, electrolytes, etc.) in the material to be analyzed or detecting the effect of the material to be analyzed on an electrical circuit (e.g., change in voltage, current, electromotive force, potential, impedance, resistance, or conductivity).
