A combined module for in-situ diagnostics of local plasma parameters and ion mass spectrum in the linear plasma device PR-2 is presented. The module consists of a stationary mass-spectrometer and a probe system containing several Langmuir probes. The mass-spectrometer is based on a classical scheme of static magnetic ion separator with 180° deflection using the background magnetic field of the plasma device, which allows us to measure both positive and negative relative ion fluxes simultaneously during the experiment. An example of a mass spectrum obtained with the device for a plasma of mixed hydrogen and air is presented.
