Abstract
A meter for measuring UV light having wavelengths, preferably between 205 nm and 237 nm. The meter includes at least one UV sensitive photo diode adapted for detecting the wavelengths of UV light between a lower end and an upper end; a first filter that blocks the UV light having wavelengths below 237 nm down to at least the lower end that the UV sensitive photo diode can detect; a second filter that blocks the UV light having wavelengths above 230 nm up to at least 205 nm; at least one amplifier for amplifying a signal from the UV sensitive photo diode; an analog to digital converter; a microprocessor; a battery in electrical communication with the microprocessor. The microprocessor preferably being in communication with the amplifier and the analog to digital converter. The microprocessor provides a result for the UV light that the UV sensitive photo diode is exposed to.
