The Bibby Scientific Jenway model 6051 colorimeter provides routine colorimeter determinations over the visible spectrum.
- With eight in-built filters with thumb wheel selection
- Transmittance, absorbance and concentration modes
- Excellent sampling flexibility
- Mains or battery operated
The concentration ranges are electronically linearised and give fine and coarse control over absorbance readings. In this mode and using most methodologies, concentration becomes direct reading. Eight in-built filters are provided enabling use in commonly encountered determinations over the range 400 to 710nm. The filters are selected by a thumb wheel. Also fitted with a recorder output.
