Spraytec Per analisi in tempo reale ad elevata velocità della dimensione di goccioline liquide anche  altamente concentrate.
Per la caratterizzazione granulometrica di spray, aerosoli, sospensioni ed emulsioni.

 Ampio campo di misura
Lo strumento con solo due lenti ha un ampio range di misura: 0,1 - 2000 um. E' composto da un'unità laser e unità di rivelazione sigillate, banco ottico, unità di controllo posizionabile a varie distanze. dall'analizzatore.
Capacità di analisi ad alte concentrazioni
L'analisi dello spray in tempo reale, fino a 10 KHz (un'analisi ogni 100 microsecondi), consente di rilevare piccole fluttuazioni temporali nei pattern dello spray e permette di analizzare spray di brevissima durata. Una routine di analisi 'multiple scattering', brevettata, consente l'analisi di spray con un livello di oscuramento fino al 95%
Certificazione
Sono disponibili protocolli IQ/OQ come stabilito dalle GAMP


flessibilità della configurazione
 Le caratteristiche personalizzabili consentono al ricercatore di configurare lo strumento in modo da venire incontro alle sue esigenze specifiche.
Gamma di trigger disponibili
Sono disponibili trigger multipli, per facilitare la sincronizzazione  delle analisi con l'impulso dello spray. Tra questi, manuale, a trasmissione, con varie modalità.
