ABSTRACT:
The indicator terminal for a coulometric measuring device includes a terminal body with a conically shaped inner space that is coaxial with a tubular nozzle situated in the terminal body. The inner space intersects with a contact mouth formed as a cylindrical recess at a base end portion of the terminal body. A measuring edge of the contact mouth is defined at the base end of the terminal body. The tubular nozzle has a terminus at a predetermined distance before the base end of the terminal body near the contact mouth. Centering and supporting means for the tubular nozzle include three ribs that project across the inner space to engage the periphery of the tubular nozzle and extend along the nozzle in helical fashion so as to be nonparallel with the axis of the nozzle. A reinforcement in the terminal body helps prevent distortion of the contact mouth when the terminal is pressed against a metallic surface.
