An improved interfacing system has been provided for processing data values in the form of rapidly occurring analog pulses from an analytical photometer into a digital computer. The interface comprises an electrical circuit having a data sample-and-hold section that provides data values to an analog-to-digital converter for reading into the computer. A gating circuit is provided which, when enabled by the computer, allows the computer to sense the first of a series of data pulses to provide an address signal into the computer for addressing the following series of pulses in the computer memory taken from the analog-to-digital converter. The computer may communicate with several interfaced photometers by means of programs held in storage whereby the data values are automatically processed according to the analyses being performed by the photometers.
