The meter is specifically designed for measuring
the temperature in many chemical processes that take
place during the beer production including mashing, wort
separation, fermentation and finally packaging, distribution
and aging.
Both air temperature and product internal temperature can
be measured with this thermometer.

tank, the boil kettle, fermenter, bright beer tank and final
storage area. Temperature checks provide peace of mind
the operation is running smoothly and the batch will be
uncompromised.
