Spectrophotometer photoLab® 7600 UV-VIS

WTW Spectrophotometer photoLab® 7600 UV-VIS

The spectrophotometer photoLab® 7600 UV-VIS combine routine analysis with spectral analysis and pioneering procedure OptRF

  • Menu-guided operation
  • OptRF for standard parameters COD, NO3, NO2 in the outlet of municipal wastewater treatment plants
  • Multi-layer AQA
  • Application support
  • Comprehensive programming opportunities

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
  • 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 put out directly as concentration reading, without the use of reagents. No potassium dichromate, no digestion - for quick testing. The composition of the water is very important for this calculation, since water is not equal to water.

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. Being light-weighted and powered by car battery, photoLab® 7600 UV-VIS can be operated On-site easily.

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. You will find all important information about SAC in the following article as part of the photometry dictionary: "SAC is not equal to SAC".

Well-proven routine analysis and wide-ranging application support

Simple measuring: photoLab® 7600 UV-VIS from 190 – 1100 nm supports the fastest and affordable routine analytics by using barcoded test kits and round and rectangular cuvettes just like the VIS version photoLab® 7100. 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 PC software photoLab® color + Data spectral offer comprehensive color measurement and a 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.
