Tester dedicated for scattering turbidimetry

The utility model relates an automatic detecting chemical analyzer field, in particular to a dispersion turbidity detecting device in an albumen analyzer, which comprises an optical path section which comprises an optical emitter, an optical path and a transparent container for holding detected objects, and a photoelectricity detecting section which comprises a light dispersion receiving module, a phtoelectricity transformation module and a detecting module. The light emitted by the light emitter is transmitted through the optical path to the transparent container for holding detected objects, and the light dispersed by the transparent container is transmitted to the photoelectricity section. The photoelectricity transformation module comprises a photoelectricity sensor and an adjustable bleeder circuit, and the electronic signals sent by the photoelectricity sensor are transmitted to the detecting modules after voltage division. Only the adjustment of the voltage values of the bleeder circuit is required to produce a detecting instrument with consistent results by a plurality of detecting instruments due to the adjustable voltage division circuit equipped in the photoelectricity transformation section, thereby being simple and available with low cost.
