Colorimeters Brinkmann Dipping Probe Colorimeters (available in four models) come with fiber optic bundles to read transmittance, absorbance, or concentration. The fiber optic probe tip is dipped di­ rectly into the sample solution. Read­ ings may be taken in luminous or nonluminous environments. Applications in­ clude colorimetric titrations, turbidity measurements, and in-line monitoring. Model PC/700 features an analog scale and a single slide-in filter; model PC/ 7 0 1 , an analog scale and multiple filter wheel; model PC/800, a digital readout and single slide-in filter; and model PC/801, a digital readout multiple filter wheel.
