Fast Photometer FPM01-LR
The Fast Photometer FPM01-LR is a cutting-edge, versatile tool designed for the quantitative measurement of the muzzle flash of firearms. This advanced photometer exists in two modifications: one measures in the visible light according to CIE specification, while the other measures in the area of visible and infrared light (up to 1100nm), ensuring that it can meet the needs of a wide range of applications.
For accurate and reproducible measurements, the FPM01-LR features a built-in laser rangefinder with a camera, allowing users to precisely aim the detector to the muzzle of the barrel and position the detector at a defined distance from the muzzle. This ensures that the photometer captures accurate and reliable data, making it an essential tool for professionals in need of precise muzzle flash measurements.
In summary, the Fast Photometer FPM01-LR is a powerful, accurate, and versatile tool that is indispensable for professionals in need of quantitative measurements of the muzzle flash of firearms.
