PROBLEM TO BE SOLVED: To provide a measuring device for the quantity of mercury in a lamp and a measuring method thereof capable of conducting non-destructive measurement of an effective quantity of mercury in the lamp easily and accurately by measuring aging effects of a lamp voltage and a lamp current. ;SOLUTION: This measuring device comprises a DC power source 12 for lighting a fluorescent lamp 11, a voltmeter 13 for measuring a voltage applied to the fluorescent lamp 11 by the DC power source 12, an ammeter 14 for measuring a current flowing through the fluorescent lamp 11, a Peltier element 15 for cooling a part of the fluorescent lamp 11, a thermometer 16 for measuring a peripheral temperature of the fluorescent lamp, and calculating means 17 for calculating a quantity of mercury of the fluorescent lamp 11 by using signals from the voltmeter 13, the ammeter 14, and the thermometer 16. An effective quantity of mercury in the lamp is measured from aging effects of a lamp voltage and a lamp current in DC-lighting the lamp with this measuring device of a quantity of mercury in a lamp and this measuring method thereof.;COPYRIGHT: (C)2000,JPO
