The SpectroDirect is a modern single-beam spectrophotometer with an excellent price/performance ratio that is specifically designed for water testing. The light source is a tungsten halogen lamp with flash function. The lamp is switched on only momentarily during of the measurement process, so there is no need for a warm-up period. The SpectroDirect is ready to perform a self-test as soon as it is switched on.


Multifunctional Sample Chamber

Round vials measuring 16 mm and 24 mm in diameter and rectangular cells with pathlengths from 10 to 50 mm may be used without an adapter. Only the 10 mm cell will be fixed by a little holder that must inserted into the sample chamber.



  • Pre-programmed Lovibond methods
  • Absorption
  • Transmission
  • Spectral data recording
  • User calibration (polynomials)
  • Concentration (linear)
  • Kinetics



After it is switched on, the SpectroDirect automatically performs a self-test - beginning with a function test of the stepper motor and the halogen lamp, followed by an optics test. For this purpose, the unit has a built-in didymium glass filter. This filter checks the correct wavelength setting. If the wavelengths are incorrect, the optical system is automatically adjusted during the self-test.



The only maintenance that is required is replacement of the light source. The lamp is situated at the back of the photometer in an easily accessible position. Changing the lamp is fast and simple and does not required ay tools.


N.I.S.T Traceability

This spectrophotometer can be tested using a Secondary Standard Filter Set which is N.I.S.T. traceable. Furthermore the instrument may be calibrated for each method in a "user calibration mode" with N.I.S.T. traceable standards.
