Features

Two measurement modes available

There are two measurement modes. One is Manual mode which needs to start up or end of measurement manually. Another is automatic modes that can automatic switch-on or end of measurement when the energy intensity emitted by the light source is above or below the trigger threshold that can be set

Four interfaces help you record the data of UV light source

There are four interfaces to help you know better about UV light source you tested: In maximum values interface, you can acquire cumulative energy value, maxiumum power value and maximum temperature value. Measurement time can be recorded in RT interface. In temperature and power curve interface, you can know the temperature change and energy intensity variation of the light source. Four interfaces can be switched freely
