Description
The SpectroDirect is a modern single-beam spectrophotometer with an excellent price/performance ratio that is specifically designed for water testing.
The instrument is equipped with a wide range of pre-programmed methods based on the proven range of Lovibond tube tests, tablet reagents, liquid reagents and powder reagents (Vario Powder Packs).
Optics
The SpectroDirect is a single-beam spectral photometer (see illustration). The light source is a tungsten halogen lamp with flash function. The lamp is switched on only momentarily during of the measurement process1), 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.
The light passes through an entry slot to the monochromator, where it is split into spectral ranges. The monochromator is a holographically produced, transparent grating. The movable mirror ensures that light of the desired wavelength is focused automatically so that it passes through the exit slot, into the sample chamber and therefore through the water sample. The light that is not absorbed by the sample travels to the silicon photodiode detector. This signal is then evaluated by a microprocessor and shown as a result in the display.
