Spectrophotometer 190-1100 nm

Function and Applications

Spectrophotometer 190-1100 nm

Benefits

• The UV-VIS spectral photometer is characterised by its compact design and due to its wide range of possible uses
• operation is via a clearly set out overlay keyboard on the screen dialogue
• current wavelengths and measured values can be displayed in large format
• alternatively, all measured values can also be presented graphically or in table format on the LCD screen with background lighting
• strong light, high performance optics enable absorption and transmission measurements to be taken in the whole wavelength range of 200 to 1100 nm with automatic switching between the twolight sources
• a high speed scanner minimises the susceptibility to errors during a wavelength changeover and thusenables very precise measurement
• storage of measurement parameters, data, calibration curves, spectra, etc
• spectral scanning of samples with freely selectable wavelength range, automatic baseline correction and band/ trough identification
• production of a calibration curve withup to 10 concentration standards, details of the straight line formula, automatic correction against the zerosolution
• the device can be connected to aprinter or computer with a serial port via an installed Centronix or RS232interface.
