Product No: PM400F
PM400F Flashlight Photometer is an instrument designed specifically for the instantaneous photometric testing of pulsed and flashing light sources. It can operate as a standalone unit or in conjunction with LISUN LSG series goniophotometers for integrated testing. It is suitable for measuring the instantaneous photometric characteristics and effective luminous intensity of various pulsed light sources—including aviation obstruction lights, aircraft anti-collision lights, navigation lights, traffic warning lights, special vehicle warning lights, pulsed LEDs, flares, signal flares, and pyrotechnics. The device supports type testing and factory acceptance testing for flashing warning lights used in aviation, marine, automotive, and other civil applications. Featuring a detector with excellent V(λ) spectral response matching, it is compatible with diverse flash waveforms—such as square waves, irregular pulses, and pulse trains—and meets the metrological requirements of relevant domestic and international standards for flashing light sources. sources.
