Spectrophotometer PV1251C for ecology


PV1251C model

The PV spectrophotometer 1251C has proven to be a high-quality and reliable device in laboratories and centers for environmental monitoring and analysis of water. PV1251C is used for qualitative and quantitative analysis of natural objects: analysis of atmospheric air and industrial emissions into the atmosphere, control of water quality (drinking water, water supply, waste water, industrial, natural, etc.), environmental monitoring of soils, etc.

  • Any techniques
  • Different types of cells (including — CPP)
  • Convenient construction of cell section
  • Operates as with the computer, and autonomous
  • High accuracy of measurements

Any modes

The spectrophotometer PV1251C is open system, the user can independently select and program necessary modes (to 100 modes)

Different types of cells

It is possible to use standard cells and CPP cells (with length of optical way from 5 up to 50 mm)


From fiberglass. It is painted with chemically resistant color

Convenient at operation

The spectrophotometer "SOLAR" is convenient for working by the laboratory assistant. Convenient construction of cells separation: the cover is removed by the slider principle - it is conveniently to remove cells. It is conveniently to operate in standalone mode (without connection of the computer) thanks to the big built-in keypad and the informative LED screen where hints are displayed

Connection to the computer

Expands possibilities of mathematical processing of results, allows to process ranges, to create and save databases, etc.

Convenient software

  • High accuracy of measurements
Existence of the double monochromatic device provides the minimum level of the hindering radiation that guarantees high accuracy of measurements
