The Joint Research Centre of the European Communities has issued a restricted invitation to tender for a phase Doppler anemometer for the determination of the concentration, size and velocity of particles suspended in gases. As the equipment will be moved between different facilities in both nuclear and non-nuclear laboratories, instrument installation and adjustment of the optics should be as straightforward and as easy as possible.
