Device description
The pH measuring device BW10 is suited for measuring pH
values and temperatures of liquids.
With the automatic temperature compensation and the
automatic calibration functions the measuring device permits a
quick and precise determination of the pHvalue between pH0
and pH14 in the temperature measuring range between 0 and
50°C.
The three-point calibration is already carried out before leaving
the factory, but it can also be repeated using the supplied
pHbuffer solution set.
The determined pHvalue is displayed along with the water
temperature.
The device comes equipped with an exchangeable pH electrode.
The electrode and the water temperature probe are protected
from external influences by means of a removable protective
cap.
The device is further equipped with a Hold function for holding
the currently measured value.
