At the center of Gossen's certification light metering system is the MAVOMASTER, a compact, all-in-one control and display unit that generates and stores lighting measurements when used with any MAVOPROBE. The MAVOMASTER interprets MAVOPROBE readings in both absolute and relative values, calculates derivative values, and charts these values over time to provide the user with an in-depth understanding of any lighting environment.

The unit takes one AA battery and has 8GB of internal storage that functions as an external drive when connected to a PC via USB and used with MAVOSOFT software for Microsoft Windows. Only one MAVOPROBE can be connected to a MAVOMASTER at a time.
