摘要：NOVELTY - The photometer has a base provided with a detecting bracket. A test paper groove is utilized for placing a test paper. A shielding plate is provided with a detection hole that is fixed on a base. A shielding plate hole is located on an LED light source. A photo-electric converter i.e. photodiode, is provided with the shielding plate. A middle end of the shielding plate is fixed with the test paper along length direction. The LED light source irradiates incident light on the test paper through a light channel. The incident light is received by the photo-electric converter. USE - Portable multi-passage test strip reflection photometer. ADVANTAGE - The photometer occupies less space and eliminates influence of background light, and has low energy consumption, quick detecting speed and high measuring precision. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a portable multi-passage test strip reflection photometer.
