Mettler Toledo Easy VIS analytical instrument

Mettler Toledo’s Easy VIS analyses liquid, translucent samples for their optical spectrum, colour and water parameters. The compact instrument is designed to take over the measuring tasks of a colorimeter, a spectrophotometer and water testing methods such as titration.

A typical place for product is the QC lab at small manufacturers in the food and beverage industry, environmental testing labs or any industry needing quality control and supervising their process or wastewaters.

It may be used during multiple steps of the production process, including the inspection of raw materials, quality control of semi-finished and finished products and testing the water quality of wastewater.

It contains a visual user interface with workflow guidance and operates within a wavelength range of 330 to 1000 nm. Its light source is a tungsten lamp that can be easily replaced when needed.

The instrument comes with 25 pre-installed standard-compliant colour scales such as ICUMSA for sugar colour, ESBC for beer quality analysis and OIL CIELab for wine colour determination. For spectrophotometry, the sample is analysed at the wavelengths where the sample has its absorption of light. It measures the transmitted or absorbed light and reveals the sample’s concentration or purity.

In the testing procedure, one cuvette holds the blank measurement and another is prepared with the sample. After the analysis method is chosen, the cuvette is placed in the cuvette holder and the PathDetect function recognises which path length is measured. The measurement begins when the lid is closed and results show up on the screen. The EasyDirect software allows for results to be saved automatically or exported to an external storage device or data management system.
