Go Direct™ Light and Color Sensor
CHF 222.20*
Go Direct Light and Color Sensor combina la potenza di più sensori per misurare l'intensità luminosa nella gamma visibile e nelle porzioni UV dello spettro elettromagnetico.
Sensore di luce visibile
La rapida frequenza di campionamento del sensore di luce visibile (1000 Hz) consente di osservare lo sfarfallio delle lampade fluorescenti.Sensore di colore rosso, verde, blu (RGB)Utilizzate il sensore RGB per determinare il contributo relativo della luce rossa, verde e blu. Un LED bianco incorporato fornisce un'illuminazione uniforme quando il sensore è posizionato direttamente sopra una superficie, riducendo l'effetto della variazione della luce ambientale.
Sensore UV
Ideale per esperimenti con luce solare e lampade UV, il sensore UV risponde bene alle radiazioni ultraviolette nello spettro UVA e UVB.
Idee di sperimentazioneIl sensore Go Direct Light and Color Sensor può essere utilizzato in una varietà di esperimenti:
Esplora l'intensità della luce in funzione della distanza.
Effettuare studi sui filtri polarizzati.
Osservate lo sfarfallio delle lampade fluorescenti.
Eseguire studi di riflettività, compresa l'analisi cromatica.

Go Direct™ Conductivity Probe
CHF 295.60*
The Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.
Go Direct Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab and then make measurements outdoors without temperature changes affecting data. This temperature compensation can be turned off to perform conductivity studies as a function of temperature.
The Go Direct Conductivity Probe has a range of 0 to 20,000 μS/cm to provide optimal precision in any given range. An alternating current at its electrodes prevents polarization and electrolysis, reducing contamination of solutions.
