  • Page 5: Principle Of Operation

    The optical system of HI 83099 is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

  • Page 6: Functional Description

    The measurement process is carried out in two phases: first the meter is zeroed and then the actual measurement is performed. The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both the measurement and the calibration (zeroing) cuvette are optically identical to provide the same measurement conditions.

  • Page 9 • Proper use of the powder reagent packet: (a) use scissors to open the powder packet; (b) push the edges of the packet to form a spout; (c) pour out the content of the packet. USING CUVETTES • Proper mixing is very important for reproducibility of the measurements. The right way of mixing a cuvette is specified for each method in the related chapter.
  • Page 10 • Pay attention to push the cuvette completely down in the holder and to align the white point on the cap to the indexing mark on the meter. • In order to avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic stopper and then the black cap.

  • Page 11: Health & Safety

    HEALTH & SAFETY • The chemicals contained in the reagent kits may be hazardous if improperly handled. • Read the Material Safety Data Sheet (MSDS) before performing tests. • Safety equipment: Wear suitable eye protection and clothing when required, and follow instructions carefully.
