Demonstrator model
Encyclopedia
A Demonstrator model is an example of something (most often a physical object) used in some kind of presentation or exhibit.
and marketing
people often need to show off an example of the product they are trying to sell, and demonstrate the use of the product. This has been accomplished in a variety of ways.
In some cases, a standard or production version of the product will be used; the salesperson simply carries the product around, and may even sell the item they are presenting and replace it with another.
In other cases, special variants of the product will be used. These have features designed to aid in sales, such as having sections of the product manufactured so as to make the internals of the product more visible, often through the use of transparent plastics. One example of this type of demonstrator is the Demonstrator pen
, a partially (or wholly) transparent sales demonstrator for Fountain pen

demonstration models have been made, as well as other small manufactured mechanical objects. These can easily become collectibles, as they are both rare (compared to the object that they are demonstrating) and can be interesting to look at.
In cases where a product may be non-portable, custom built, not yet completed, or too expensive to allow for a unit to be used only for demonstration purposes, a Scale model
or non-functional full-size mockup
may be used. IBM

. This demonstrator was packaged in its own briefcase and could be carried on sales calls, then set up to show a miniature version of the large multi-million dollar device.
In the case of large items, such as automobile
s or railroad rolling stock
the manufacturer may designate one or a small number of the units as dedicated demonstrators, though they may be later sold to customers. Sometimes these units are prototypes or examples from the early stages of series production, and may not be identical to later units. Frequently demonstration models of this sort will be the fanciest versions of the products, with extra or optional features included in order to show off those features and to entice buyers.
devices are used in lessons about electricity
, and models of basic devices such as blocks and tackle
are used to show certain physics principles.
Educational demonstrator models may be used to allow a participant the opportunity to experience something in a non scientific controlled environment. The Dwipod (Driving While Intoxicated Portable Onsite Demonstrator) offers students the opportunity to experience impaired driving in a non scientific controlled environment. This is an example of a Educational demonstrator.

Educational demonstrator models
Especially in science classrooms, but also in many other fields and locations, models can are used either as visual aids or to demonstrate a principle or process. For example, small Jacob's Ladder spark gapSpark gap
A spark gap consists of an arrangement of two conducting electrodes separated by a gap usually filled with a gas such as air, designed to allow an electric spark to pass between the conductors. When the voltage difference between the conductors exceeds the gap's breakdown voltage, a spark forms,...
