Colour Measurement of Liquid Chemicals

For transparent or semi-transparent liquids

Colour Measurement of Liquid Chemicals

Spectrophotometers for liquid chemical products from opaque to translucent in reflectance or transmission.

For manufacturers of liquid chemicals products, our portable and benchtop colour measurement instruments and software help to produce accurate and consistent coloured chemical products. You can analyse liquid chemical products of all levels of opacity to produce repeatable and traceable spectral data that can be reported, recorded, and communicated with customers.

Konica Minolta Measuring Instruments can help you to control costs, specify and deliver the products your customers want, and provide a competitive edge in the market.

Manufacturers in a wide range of markets need to offer a consistent and traceable product, and rely on our instruments to provide fast and accurate measurement of water or oil-based liquids, whether opaque or transparent.

Konica Minolta’s versatile benchtop spectrophotometers can be used connected to a PC or in standalone mode allowing for colour control where you need it, either in the laboratory, in production, or onsite at a customer or supplier.

Our benchtop spectrophotometers are widely used for both transmittance and reflectance colour measurement of liquids, generating colour data that is easy to analyse, report, and communicate with customers. Cuvettes of 2, 10 or 20mm are available in either optical glass or plastic dependent on your requirements. Or a flow cell can be employed to integrate the system into other test equipment or with an automated or closed system.

Our benchtop spectrophotometer CM-5 can measure several of the standard color indices commonly used in the chemical field. Spectral curves for specific indices including Gardner, Hazen/APHA, Iodine Color Number, European Pharmacopoeia, and US Pharmacopeia are stored in CM-5, eliminating the need to prepare and handle the standard solutions for each index. Index measurements can be taken using the optional 10mm cell measurement with the commercially available 10mm-wide cells used for other types of chemical analysis, letting our instrument easily fit into your current workflow.

Our experienced teams can recommend a solution, and our extensive service network can ensure that your instruments are maintained and traceable throughout their life.
