The 400 series is a modular system of signal processing electronics which provides a computer interface via the 417 for all of the optical detectors used in light measurement systems.
All the modules are housed in one of the 417 bins which include the necessary stabilised power supply, output display facilities and an integrated USB computer interface. The module parameters can be accessed either manually or via the USB interface by a computer.
