PROCESS ANALYZING ARRANGEMENT

The invention is directed to a process analyzing arrangement (10) for continuously determining a water parameter of water (14) of a stationary water site (12), with an automatic analyzer unit (100) and a water sample feed pump (30) for pumping a water sample flow from the stationary water site (12) to the automatic analyzer unit (100),The automatic analyzer unit (100) comprises:a physical analyzer (66) with an analyzing chamber (60) where the water parameter is physically determined,a separate grab sample container (110) of at least 20 ml for collecting a grab sample volume, anda fluidic control arrangement (200) for selectively directing from the water sample flow an analyzer sample to the analyzing chamber (60) and/or a grab sample to the grab sample container (110),wherein the fluidic control arrangement (200) comprises an electronic control unit (90) with a grab sampling control (92) and a grab sampling criterion means (94,95,96) for initiating a grab sample action controlled by the grab sampling control (92).Since the automatic analyzer unit can provide a grab sample, no manual grab sampling is necessary anymore.
