The photoLab® 7000 series of UV and UV-Vis spectrophotometers combine routine and spectral analysis in one unit. OptRF (Optical Reagent Free) COD, NO3 and NO2 functionality is included on the UV-Vis model. OptRF is a new innovation from WTW that allows for the measurement of COD and Nitrate/Nitrite in waste water without the need for digestion or hazardous reagents.With new reference beam optics and a colour display, multi-wavelength and multi-step readings allow for complex operations including enzymatic analysis of standard parameters with the option of user-defined programming. Key features and benefits include:

• Routine analysis with barcode recognition and automatic measurement range adaption for all cuvette sizes
• CIE-compliant and other colour measurement options with optional PC software package photoLab® color and photoLab® Data spectral
• OptRF – reduce cost, reagent usage and hazard with reagent and digestion free COD, Nitrate and Nitrite waste water measurement
• 5,000 measurement values can be stored or ~500 spectra (300-900nm)/400 kinetics with 150 measurement values
• 200 + methods for routine analysis with commercial test kits, 1,000 user defined or 20 profiles for kinetics and spectra
• Special methods such as NH3, CO2, colour, SAC, Chlorophyll and selected enzymatic test including glucose
• Brewery package option
• Suitable for onsite use and equipped with comfortable matrix adjustment for IQ Sensor Net with IQ-LabLink®
