Microprocessor Spectrophotometer

Product Code: AVI-574 Category:

A Versatile, Rugged, Accurate & Easy to Operate Instrument to determine Absorbance, Transmision, Concentration and K Factor

MICROPROCESSOR SPECTROPHOTOMETER is a compact and easy to operate instrument for Spectrophotometric analysis of a solution of any concentration. Theoutput is available on 16X2 line LCD display in terms of %age Transmission (%T), Absorbance (Abs)Concentration (Conc)& K-Factor. This instruments has 100 sample storage memory, printer output for priting of data on any dot matrix printer with centronics interface.
RS-232C interfacefor computer can be provided on request. The use of Microcontroller hs made it extremely versatile and state-of-the art instrument. 10mm path length test tubes and cuvettes facility is provided.

The instrument operates on wave length range between 340 to 960nm. The use of diffraction grating od 600 lines/mmi the monochromator produces a liner spectrum, An automatic shutter is provided to stop the light reaching the photodiode, when test tube is not inserted in the tube holder. This is extremely useful instrument for quantitative analysis. This instrument is useful in chemistry labs, mineral water testing labs, pharmaceutical labs, universities, hospitals, research centers, biotechnology labs, drugs & agricultural labs etc.
