    The measurement- and experimentation-system CHEMBOX / CHEMEX consists of the universal interface CHEMBOX and the data acquisition software Chemex. The sensor-inputs represent a combination of analog and digital input. Signals,recorded with the sensors, are converted by the interface CHEMBOX into computer-readable signals. Apart from the sensors, provided by IBK (conductivity sensor, pH electrode, redox electrode, temperature sensor, drop counter), all analog devices can be used, whose output voltage is not larger than 32 V. These instruments can be connected to the sensor inputs 1 and 2 (identical in function) or also to the pH / mV-input. In the latter case an external input voltage may not have values outside the range - 6V ... + 6 V.

    the site also lists lots of experiments using data logging.
