UV Detector LCD 2083.7
Description
Spectrophotometric detector LCD 2083.7 with continuously variable wavelengths in the range of 190 – 360 nm is equipped with four cell for preparative chromatography. The cells work simultaneously on the same wavelength. Output signal is available in analogue and digital form too.
The detector is equipped with a high standard IST deuterium lamp in a special socket making possible an easy changing.
The unit is easy for operating, reference and sample signal is available for detector diagnostics and lamp live reading. It is possible to control it using keyboard or external signals.
