Instruments that measure ultraviolet and/or visible light absorbance of a sample; they are based on the Beer-Lambert law, which states that the concentration of a solute is proportional to the absorbance of the sample. Accessories available.
Designed for the laboratory, this COD colorimeter is a single parameter instrument for determining chemical oxygen demand index in water for markets such as wastewater, food & beverage, aquaculture, and agriculture.
Mettler Toledo Easy Vis Spectrophotometers measure visible light at multiple wavelengths with the Tungsten Lamp. Scan the UV Vis spectrum and record patterns with the peak finding function. 25 built-in color scales are included to receive results faster.
