The Brinell, Vickers and Rockwell Hardness Testing Unit consists of a hardness testing machine that determines the three main types of hardness (Brinell, Vickers and Rockwell) in metals, hard alloys, quenched steels, etc. The Rockwell method generates a small size imprint during the test. It employs small quenched steel balls of different diameter or cones made of diamond for the indentation.
A penetrating ball of specific diameter is used in the Brinell hardness test to press the surface of the test piece with a specific force. The unit employs balls of 2.5 mm. and 5 mm.
Besides it can also be used to measure the hardness of other materials, such as rigid plastics, bakelite, etc.
The Vickers method allows to measure the hardness of practically all metallic materials, regardless their state and thickness. It employs a square base pyramid-shaped indenter. Such indenter is applied perpendicularly to the surface whose hardness is going to be measured.
The most common method used to calculate the hardness of a metal is measuring the indentation strength with the aid of a tool of specific geometry. It consists on measuring the imprint generated when exerting a preset load on the test piece for a certain time.

On the panel's right side, it is placed the system with which the test specimen is loaded. This system is composed by a sping balance, which is joined to a threaded spindle by its upper end, while on its lower side, it is joined to an articulated guided system, in which it is held the right side of the test specimen. When turning the threaded spindle clockwise, we transmit a vertical force upwards to the test specimen.
On the lower panel of the unit, it is fixed an electric motor which axis is joined to an end of the test specimen (test bar) by means of a coupling. As well, this axis has a disc, which by means a device will count the number of turns of the motor.
In order to guarantee the force verticality, the system has two guides to avoid horizontal displacements during the transmission of stress.
The applied force can be directly measured using the spring balance.
On the upper panel, the unit control box is mounted, containing: the main (on/off) switch of the unit; the cycle counter that shows us the quantity of turns the motor's axis carries out; the motor's speed control that permits us increase or diminish the turning speed of the electric motor; the motor speed display that shows us the frequency in Hz, which is being transmitted to the motor at every moment; and the on/off switch of the electric motor.
Likewise, in order to assure the constant application of the load, besides of allowing the test specimen rotation on its axial axis, the system also permits the alignment of the coupling with the test specimen, due to the deformity suffered by bending.
Both the area where the test specimen is located and the motor axis outcome are covered with a protection cover, without it the unit does not work, since it is provided with a safety system to avoid accidents.

Once the trainee has built a ventilation system independently, the effects of bends, branches, regulator flaps on the airflow rate, the air velocity, as well as the pressure loss can be investigated. The components are the same as those used in ventilation engineering.
