Digital UV - VIS Spectrophotometer-371

Digital UV-VIS Spectrophotometer 371 is a single beam, accurate, reliable and versatile instrument for spectrophotometric analysis of any concentration. The output is available on a 3 ½ digit red seven segment LED display in terms of %Transmission (%T), Absorbance (Abs.), and Concentration (Conc.).

An accurate 190.0 to 1000.0 nm wavelength control, with a resolution of 0.1 nm is obtained by microprocessor controlled stepper motor. The wavelength is displayed on 4 digit red seven segment LED display separately. A monochromator using Czerny-Turner mounting technique with 1200 line/mm grating is used

It is an extremely useful instrument for chemical, pharmaceutical, agricultural, biotechnological labs, hospitals, engineering & medical colleges, universities & research institutions.
