• Standard methods such as UVT, SAC, coloration or chlorophyll
• Multi-level AQA
• Comprehensive programming opportunities
Routine at it’s best
photoLab® 7100 VIS supports fast and affordable routine analysis via barcoded test kits for round and rectangular cuvettes. More than 250 methods are available for waste/drinking water, food & beverage industry as well as production, environmental monitoring or fish farming:

• Easy to use: place cuvette, read measurement value
• More than 250 test programs for water analysis, galvanics and general lab analytics
• Cell and reagent test kits with barcode for automatic program selection
• Automatic cuvette and measurement range detection for rectangular cuvettes
• Top reliability due to menu guided comprehensive Analytical Quality Assurance – AQA
• Measurement “Light” on the road with car battery use
• USB and Ethernet-connections for easy update, print to PDF or printer, storage and data export

From Food to Science

Special procedures for environmental and food parameters such as chlorophyll can be executed handy and clearly arranged due to an excellent menu guidance:
• Programmed multistep- and multiwavelength methods
• Comprehensive programming options for user defined requirements
• Spectra and Kinetics measurements
• Training of basics and modern photometry in education

photoLab® color: Color measurement instead of color perception

Color determination by means of photometric measurement has increased the accuracy and comparability in general compared to subjective perception of visual color measurement procedures. Color measurement is essential for many applications: from water analysis to food & beverage and quality control in production processes. Color values being a quality factor mostly lie within a certain user-specific tolerance range.

With photoLab® 7000 / 6000 Series and the optional PC-software photoLab® color common measurement procedures can be performed in a handy and neatly arranged way.
