PM400F Flashlight Photometer

PM400F Flashlight Photometer is a precision instrument engineered for photometric measurement of transient light sources. Utilizing a 16-bit high-speed analog-to-digital converter to capture flashlight output signals, the integrated microprocessor analyzes and calculates continuous time, flash frequency, effective light intensity, instantaneous maximum and minimum light intensity, and average light intensity parameters.
