LASA AGRO 1900 Mobil

LASA AGRO 1900 Mobil

The ideal set for mobile applications

Mobility and flexibility are very important factors with regard to successful operations – fast and appropriate actions are prerequisites for the best possible yields. In the field of plant nutrition, these actions can only be taken on the basis of reliable and fast analysis results.

The mobile system LASA AGRO 1900 provides the possibility of fast and precise on-spot-determinations. The complete equipment is packed in two rugged cases.

With over 220 pre-programmed HACH LANGE and HACH methods in a waterproof, shock tested design this spectrophotometer delivers lab quality results in a portable, field ready instrument. The photometer scores in all applications in the field, wherever and whenever it shall be used. Even in dusty and wet environments where other devices cannot be used, you can easily perform your
analyses with the LASA AGRO 1900.

The instrument has a large, user-friendly display and provides a simple menu navigation for easy analyses procedures even under harshest conditions. The light source of the photometer is a Xenon Flash which is only switched on for measurements because of power saving reasons.

The LASA AGRO 1900 evaluats all LCK cuvette tests. The measuring results can be carried out in
  • mg / 100 g soil
  • mg / liter substrate
  • mg / liter solution

In contrast to the LASA AGRO 3900 the test cuvette is not recognized via the barcode but the desired parameter must be selected from a list. The prepared test cuvette is inserted and the measurement is started by pressing a button. The LASA AGRO 1900 stores up to 500 readings that are read out via a integrated plug-in mini USB interface.
The readings can easily be transferred into any table formate, e.g. in MS Excel.
The supplied plug-in is also the AC adapter and battery charger of the photometer.

Together with the extraction case, this is the optimal equipment for mobile applications. The mobile system LASA AGRO 1900 is an advantageous solution for
  • Horticultural plant producers with different production locations
  • Peat, substrate producers with different production locations
  • Advisory associations with different locations
  • Consultants and service partners in hortiand agriculture

Only LASA AGRO photometers supplied by STEP Systems are specially programmed for agricultural use with direct evaluation in mg / 100 g soil, mg / l substrate and mg / l solution.
