microprocessor uv-vis double beam spectrophotometer

The Microprocessor UVVIS Double Beam Spectrophotometer LI2802 R is a highprecision analytical instrument used for measuring the absorbance and transmittance of samples in the ultraviolet and visible regions It operates over a wavelength range of about 1901100 nm and uses a double beam optical system that splits light into sample and reference beams ensuring greater accuracy and stability by compensating for fluctuations in light intensity The instrument is controlled by a builtin microprocessor which enables automatic wavelength selection data processing and multiple measurement modes such as absorbance transmittance and concentration It typically features a deuterium lamp for UV and a tungsten lamp for visible light a silicon photodiode detector and a multicell sample holder With high wavelength and photometric accuracy along with options like temperature control and data output interfaces it is widely used in pharmaceutical analysis environmental testing and research laboratories
