    The Excalibur Water Systems Ultimate Series ultraviolet power sources with integrated ultraviolet intensity detection can be used with all single lamp Excalibur Ultimate Series water disinfection products.

    This detection system was designed to minimize nuisance alarms that have plagued many of the earlier attempts by other manufactures to implement electronic ballasts with ultraviolet intensity monitors.

    As well as indicating the ultraviolet intensity level in percent, the display will indicate the number of months of lamp life remaining when the timer button is depressed.The display indicates a discrete error code if there is a malfunction of the power source or detector system to aid with diagnostics and resolution of any performance issues.
