Spectrophotometer photoLab®
- Spectrophotometers for routine and
spectral analysis from 190–1100 nm. - OptRF – the revolutionary optical
reagent free measurement of COD,
nitrate and nitrite - Photometric tasks for routine to
special applications from water to
wine - PC-driven color measurement for
quality control – from CIE to Gardner
Description
The modern, user-friendly interface makes your day-to-day work even more efficient and pleasant. Whether you
choose the photolab® VIS or the photolab ® UV-VIS with OptRF, upgrading your spectrophotometer brings many
Workflow advantages and cost savings.
In many municipal wastewater treatment plants with average loads, the innovative optical reagent-free measurement (OptRF) of COD and Nitrate is an outstanding procedure that reduces cost and environmental impact by
negating reagents used in sewage plants and environmental monitoring of surface waters.
