Bellstone The Microprocessor UV/VIS Spectrophotometer, BHI-LSR-417 is a single beam compact and easy to operate instrument for spectrophotometer analysis of a solution of any concentration. The output is available on 16x2 line LCD display in terms of % Transmission (% T), Absorbance (Abs), Concentration (Conc) and K Factor. This instrument has 100 sample storage memory printer output for printing of data with any dor matrix printer. RS-232C Interface for computer can be provided on request. The use fo microcontroller has made it extremely versatile and state-of-the art instrument. 10mm path length cuvettes facility is provided.

The instruments operates at wave length between 190 to 1000 nm range. Diffraction grating of 1200 lines/mm in the monochromator produces a liner spectrum. An automatic shutter is provided to stop the light increases the lige of phodiode tremendously, Deuterium lamp (D2) is used in the range 190 to 350 nm and Tungston Halogen lamp (W) cover 350 to 1000 nm.

This is extremely useful in chemistry labs, Mineral water teesting, Pharmaceutical labs, Universities, Hospitals, Research Centers, Biotechnology, Drugs & Agricultural labs. This is extremely useful for quantitative analysis.
