Overview

The WTW photoLab® 7600 UV-VIS Spectrophotometer is suitable for universal use, from well-proven routine analysis to spectral analysis, with pioneering procedure OptRF for reagent-free measurement of COD, Nitrate and Nitrite. Furthermore, important parameters such as UVT and SAC as well as comprehensive color measurement are supported.

Product Features
  • Multipurpose meter with optical reagent-free (OptRF) measurement technology
  • Barcode support and automatic cuvette recognition
  • Standard methods such as UVT, SAC, coloration or chlorophyll
  • Multi-level AQA
  • Comprehensive programming opportunities
  • Optical Reagent-free measurement technology (OptRF) for standard parameters COD, NO3, NO2 in the outlet of sewage plants

Light weight and optionally powered by standard car battery, photoLab® 7600 UV-VIS can easily be operated on-site.

The future has arrived: Optical reagent-free measurement of COD, nitrate and nitrite (OptRF)

  • Faster than the fastest digestion
  • No costs, as no reagents or chemicals required
  • Check of measurement range
  • Environmentally friendly and no health hazards

For the standard parameters COD, nitrate and nitrite, a spectrum in the UV range is evaluated by means of complex algorithms which are based on reference spectra. The result is output directly as concentration readings, without the use of reagents. The composition of the water (matrix) is important for this value determination.

The OptRF-methods are currently being developed for sewage plant outlets. They can be optimized for the respective municipal waste water matrix by user calibration via reference values performed with standard procedures like test kits. Depending on the composition of surface waters, the methods can be used here as well after testing and verifying with reference procedures. 

UVT and SAC

For the UV-Disinfection as well as for monitoring of organic pollution these two parameters constantly gain importance: 5 programs with and without turbidity correction are offered. 


Well-proven routine analysis and wide-ranging application support

Simple measuring: The WTW photoLab® 7600 UV-VIS Spectrophotometer supports the fastest and affordable routine analytics by using barcoded test kits and round and rectangular cuvettes just like the WTW photoLab® 7100 VIS Spectrophotometer.

More than 250 methods are available for water analytics, galvanics and general lab analytics.

Environmental parameters such as chlorophyll and application procedures for the food and beverage industry are supported by programmed methods and comprehensive programming options. With its multi-wavelength, spectral and kinetics measurements, this meter is suitable for mixed applications as well as research.

photoLab® color: Color measurement instead of color perception

The optional PC software photoLab® color + Data spectral offer comprehensive color measurement and convenient data management.

IQ LabLink

IQ LabLink offers an outstanding connection between IQ SENSOR NET and lab measurement for top measurement reliability: Measurement data of IQ SENSOR NET sensors (VARiON®) can be transferred via USB stick directly into photoLab® 7600 UV-VIS and back: faultless and without cable tangle thanks to sensor identification.
