3nh,Portable Colorimeter,NR20XE

When testing products such as meat by ordinary colorimeter, the whole instrument body has to be placed in the object which not only stains the instrument, but also will let the liquid/water enter the instrument directly and bring cross contamination. However, NR20XE is a vertical structure. When measuring, it can make sure only the aperture touches the object which will not stain the instrument body.
