PM400F Flashlight Photometer is a professional instrument specially designed for the photometric measurement of flashlight or transient light sources. By using a 16-bit high-speed AD to capture the output signal of flashlight light source, the powerful microprocessor can automatically analyze and obtain the continuous time, flash frequency, effective light intensity, instantaneous maximum and minimum light intensity, average light intensity and other parameters of flashlight light source. It is widely used in the effective light intensity measurement of traffic warning lights, aviation obstacles lights, aircraft anti-collision lights, navigational lights and other flashlight light sources, and can also be used for pulse light source such as lighting bullets, signal bullets, pulse LEDs, and explosives in the measurement of instantaneous photometric characteristics.
