Schmidt & Haensch | Colorimeter


The colorimeters of Schmidt & Haensch are developed and optimised for the Sugar industry.

Lectronic reflectance-meter for the automatic color grading of crystalline sugar according to the recommendations of ICUMSA, method GS2-11 (1994)and GS2-13 (1994).

An overview of the recommended applications is:

  • Color measurement of crystalline sugar (ICUMSA Method GS2-11 and GS2-13)
  • Color measurement of liquid crystal sugar (ICUMSA)
  • Color index determination of soft drinks and wine
  • Determination of the color of extracts (coffee, ..)
  • Color measurement of beer and wort (EBC color number)
  • Monitoring of color changes as a function of time
  • Enzymatic determination
  • Bichromate measurements

  • Color is a decisive criterion when evaluating product quality. S&H develops, produces and distributes Colorimeter for photometric determination of liquid color (Coloromat 100) as well as for automatic color grading of crystallized sugar by electronic reflectance meter (Saccharoflex 2020).

    Both the Coloromat 100 single-beam photometer and the Saccharoflex 2020 reflectance meter have pre-installed methods performing sample analyses conform to ICUMSA standards.


    Schmidt & Haensch | Saccharoflex 2020

    Reliable Reflectance Meter

  • Determining the degree of whiteness of crystal sugar
  • ICUMSA compliant measurement
  • Easy calibration
  • Robust instrument designed for permanent use

  • The Schmidt & Haensch electronic reflectance-meter for the automatic color grading of crystalline sugar according to the recommendations of ICUMSA, method GS2-11 (1994)and GS2-13 (1994).

    With this instrument the reflectance factors at 495 nm and 620 nm are measured and the ratio is indicated in terms of color type numbers. The measurement is done by use of Taylor’s law and an integrated sphere. To decrease measurement instabilities caused by inhomogeneity of the sample (e.g. different grain size) a great sample surface was chosen.
    Only two standards of the Brunswick color type or ceramic standards, preferably 0 and 6 are necessary to calibrate the Saccharoflex 2020. An adjustment can be carried by using the keyboard.
    The Saccharoflex 2020 allows measurements up to 19.99 indicating units without further adjustments. LCD display with 4-button keyboard makes handling easy and standard serial interface RS 232 ensures proper printing. The adjustable working voltage provides a high service life of the lighting unit and by this, large replacement intervals. In addition the electric bulb is run by a power saving switcher which prevents the Saccharoflex 2020 from heating up, so that a continuous operation is possible without any problems.

    Schmidt & Haensch | Coloromat 100

  • 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 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.

    Features of Coloromat 100

  • Objective and repeatable measurements
  • 3 fixed wavelengths 340, 420 and 720 nm, optional 6 additional (in the range 340 – 900 nm)
  • Optional 6 further wavelengths (in the range 340 – 900 nm)
  • Automatic wavelength setting
  • Polarimeter cells up to 100 mm usable as well as rectangle cuvettes
  • Single or flow through measurement
  • Remote control via PC
  • Data output to PC or direct connected printer
  • Up to 250 methods programmable
  • Internal data storage of results
  • GLP/GMP conform documentation
