Single beam scanning UV Vis spectrometer

M501 Scanning Single Beam Spectrometer

This is the Single beam scanning UV-Vis spectrometer M501 with an on-board LED display and keypad offering local control.  The instrument can be linked and controlled by a PC via UV Analyst software.

See our NEWS for more info on the M501

The sealed and solvent-resistant tactile keypad has an alpha-numeric entry for user file names and user entry of units making it a practical and methodical instrument.  The M501 also has a real-time clock for date and time stamping of results to help with organisation and clarity of analysis.  There is also the facility to monitor the useage status of the lamps for maximum longevity and optimum performance.
