A survey of haze meters that are currently available has been carried out to find out whether an instrument(s) can be recommended for use by the brewing industry. There is a marked difference between values measured by instruments reading at 13° and 90° scatter. There are very minor differences in the haze values obtained using the various 90° instruments. Overall the Hach meter is recommended as a replacement for the Radiometer. Suspensions of styrene divinylbenzene beads were judged to be suitable as an alternative to Formazin for standardising haze meters.
