A vector is a quantity with both magnitude (strength) and direction. Like a force having a strength in pounds and a direction. Or a wind having magnitude (in mph) and direction (Northeast). A scalar has only magnitude. Like the length of a segment or amount of peanuts in a jar. Scalars are just numbers.
No, readings on a digital voltmeter are scalar quantities. Voltage, which is what a voltmeter measures, is a scalar quantity representing the potential difference between two points in a circuit. It has magnitude but no specific direction, making it a scalar.
In a given region of space, the scalar potential is related to the electric field by the gradient of the scalar potential. The electric field is the negative gradient of the scalar potential. This means that the electric field points in the direction of the steepest decrease in the scalar potential.

The potential gradient is a vector quantity. It represents the rate of change of the scalar electric potential with respect to position in space.
Magnetic moment is a vecotr quantity
An electromagnetic four-potential is a relativistic vector function from which the electromagnetic field can be derived. It combines both an electric scalar potential and a magnetic vector potential into a single four-vector.

Direction. A scalar has only magnitude, while a vector has both magnitude and direction.
Electrostatic potential is a scalar quantity. It represents the potential energy per unit charge at a given point in an electric field.
Gravitational potential energy is a scalar. Gravity also has a vector energy cmV= cP.
Magnetic force is the force between magnets or moving charges, while electric force is the force between electric charges. Magnetic force acts on moving charges perpendicular to both the velocity of the charge and the magnetic field, while electric force acts along the line connecting the charges.
