ABSTRACT:
An exemplary verticality examining apparatus (1) includes three first sensors, two second sensors, and a plurality of sensor-indicators. Outmost extremities of the first sensors cooperatively define an imaginary single plane, and are configured for physically contacting a first side of an object to be examined. The second sensors are configured for simultaneously physically contacting a second side of the object when the first side of the object contacts the first sensors if the object has verticality as between the first side and the second side thereof. The sensor-indicators are electrically connected to the first and second sensors and are configured for indicating states of the first and second sensors with respect to any physical contact with the object.
