Spectrophotometer for colour measurement
The Coloromat 100 is a spectrophotometer enables easy and reliable colour measurement of liquids. It features a continuous measuring mode with a freely configurable rate, ideal for monitoring colour changes in product streams. Transmission, extinction, and ICUMSA liquid colour units at the standard wavelength of 420 nm are included as standard features.
Easy to use
The touchscreen enables soft key functions and alphanumeric input, making it easy to enter information such as batch names and user details. Additionally, users can select wavelengths using the touchscreen. The instrument comes with three standard wavelengths and optionally integrates up to six additional custom wavelengths, enabling a broad range of applications.
Thanks to the spacious sample chamber, both polarimeter flow-through tubes up to 100 mm and standard cuvettes can be used, allowing for easy filling and high sample throughput. Moreover, using a 100 mm tube significantly improves measurement accuracy and resolution, up to ten times better than a 10 mm cuvette.
Furthermore, its sample compartment is open at both the top and bottom, preventing spills from entering the unit. With its unique optical design, the Coloromat is unaffected by stray light. This spectrophotometer also features a continuous measuring mode with a freely configurable sampling rate, ideal for monitoring colour changes in product streams over time.
