Awesome Features

Prizm+ (patent pending) introduces some of the best features in its category previously offered only in bulky and expensive benchtop spectrophotometers.
Have a look at the list of astounding features offered in the tiny pack.

Prizm+ :compact spectrophotometer

Compact design

Measures only 10x7x3 (in cms). Carry it in your shirt pocket to test on field.
