Colorimeter

Coloromat 100

PDF data sheet
  • Measurement of transmission/extinction
  • Color determination of liquid samples
  • Up to 9 fixed wavelengths
  • Polarimeter tubes up to 100 mm
  • Integrated ICUMSA Methods
Digital single beam photometer for the determination of liquid colour

The Coloromat 100 allows easy measurement of transmission, extinction and ICUMSA liquid colour units at the recommended standard wavelength 420 nm.

The touch screen is used for soft key functions and alphanumerical inputs which allow easy handling for example batch name, user etc. The wavelengths are selected via the touch screen. Three wavelengths are pre-installed as standards, optional the Coloromat 100 can be equipped with six further customized wavelengths.

This opens a wide range of applications . Due to the generous dimensions of the sample chamber the use of polarimeter flow through tubes up to 100 mm as standard cuvettes allows easy filling and a high through-put.

The sample compartment is open to the top and the bottom avoiding spillage to enter the unit. Due to its unique optical design the COLOROMAT is not affected by stray light.

The Coloromat 100 is equipped with a continuous measuring mode with free configurable sampling rate for monitoring color changes in product streams as a function of time.

The general operating software contained in the FLASH MEMORY can be updated by PC (data file downloaded from Internet or CD ROM) and has a capacity for 250 pre-programmed tests. Up to 230 tests can be stored in the RAM. The import of data by touch screen or PC are possible. Additionally up to 2970 results of max. 99 samples can be managed in the memory.
