<p><span style="font-family: Century Gothic,sans-serif;">Lo strumento è composto da due tubi di vetro fra i quali può circolare una corrente d'aria. Nel tubo interno si trova un nastro di foglio d'oro avvolto a spirale e interrotto in numerosi punti. Collegando gli estremi della spirale con un rocchetto d'induzione scoccheranno fra le interruzioni numerose scintille che generano ozono nell'aria circolante nell'intercapedine.</span></p>

<p><span style="font-family: Century Gothic,sans-serif;">L'ozono è un gas naturale che respiriamo normalmente. Si crea quando le molecole di ossigeno O</span>_{<span style="font-family: Century Gothic,sans-serif;">2</span>}<span style="font-family: Century Gothic,sans-serif;"> vengono divise, dalla scarica elettrica in questo caso, in due atomi separati. Gli atomi liberi si ricompongono a gruppi di tre formando l'O</span>_{<span style="font-family: Century Gothic,sans-serif;">3</span>}<span style="font-family: Century Gothic,sans-serif;">. L'ozono tende a reagire con molte sostanze ossidandole e neutralizza quelle inquinanti decomponendole in acqua, anidride carbonica, zolfo, etc.</span></p>
