At the initial stage of measurement, the device precisely determines the mass
of an object placed on instrument’s weighing pan. As mass reading is
stabilized, the sample is quickly heated by halogen lamps or IR emitters or a
heater in metal cover, causing humidity evaporation from the tested sample.
While sampling, the moisture analyzer is continuously checking the decline of
mass, and on calculation, it displays current moisture content in a tested
sample.
Compared to conventional methods of humidity content determination of
various substances, application of moisture analyzer MAC series considerably
shortens measurement time and simplifies testing procedure. The moisture
analyzer allows for setting multiple parameters which influence the procedure
of moisture content determination in a sample, such as: temperature, time,
drying modes, etc.).

Inappropriate use
CAUTION!
Do not open the drying chamber during drying process. Moisture analyzer
features a halogen lamp which is a very powerful heat source. Thus, user
should pay special attention no to touch those elements of a moisture analyzer
that get hot while drying procedure (i.e.: disposable pan, pan handle, and inner
shields of the drying chamber).
Remember that some of tested samples may become dangerous if heated
(appearance of poisoning vapours, danger of ignition or explosion).
A moisture analyzer MAC series is not intended for dynamic weighing. Even if
small amounts of a sample are added to taken off the weighing pan, the mass
readout should only be taken only on stabilization of measurement result
(appearance of stability pictogram
on the display
)
.
Do not place any magnetic materials on the weighing pan, as this can cause
damage of the measuring system of the instrument. Be sure to avoid impact
shock and overloading the balance in excess of the prescribed maximum
measuring range (max capacity), minus any possible tare weight that has been
applied).
Never use the moisture analyzer in an environment endangered by an
explosion. This moisture analyzer has not been adjusted for operation in
explosive areas. There must not be any modification made to the moisture
analyzer.

Principles of safety use
Use of moisture analyzer MAC series conversely to safety principles and user
manual guidelines may be hazardous to operator’s health and life. It is
obligatory to acknowledge with safety principles listed in the user manual:
