Abstract
The utility model discloses a hand-hold spectrometer which consists of a refractometer, a bar code and a detecting test paper strip, wherein the refractometer comprises a first reflector, a collimating mirror, a raster, an object lens, a second reflector, a CCD photosensitive device and a photomuitplier. The hand-hold spectrometer adopts the unique reflected light test principle for testing; incident light is absorbed by the pigmented test paper strip; the concentration of analyzed materials is calculated through measuring the intensity of the absorbed light; and the hand-hold spectrometer adopts double-beam testing, so measurement is carried out twice at the same time. The utility model has the advantages of portability, simple operation and fast and reliable results, is particularly suitable for on-site analysis, and can be widely applied to the fields of food safety monitoring and detection, environmental protection analysis and the like.
Description
Technical field
The utility model relates to hand-held spectrometer, mainly applies to fields such as food safety monitoring, environmental protection analysis.
Background technology
