Measurement instrument LabMaster-aw

LabMaster - aw
A professional laboratory instrument for a very precise
measurement of aw values (water activity) in foodstuff,
drugs, cosmetics etc.. The temp. of the measurement
chamber may be set in the range from 0°C to 50°C and
kept consistently with an accuracy of +/-0.2K.
This instrument runs the most used aw measuring
technology, the electrolytic resistive principle. The
advantages are appreciated by all users around the
world.

LabMASTER-aw
A synonym for high-precision, flexibility, versatility and measurement speed
Well-proven laboratory instrument for reproducible, precise aw
measurements under accurately controlled temperature conditions for all
types of foodstuffs, cosmetics as well as dry pharmaceutical materials. The
LabMASTER-aw is the only instrument that enables measurements under
precisely controlled chamber temperature conditions, selectable in the
following range: 0°C to 50°C, with an accuracy of 0.2K.
The device and its sensor are very robust and have an excellent long-term
stability. The Novasina electrolytic resistive sensor delivers essentially
hysteresis-free measurements. The implemented user management
systems allows a simple and intuitive operation. The system is available in
3 different versions “BASIC” (single user),”STANDARD” (multi user) and
“ADVANCED” (multi user and multi cannel). This improves considerably
the cost efficiency .
The large, illuminated graphic LC display gives a clear overview. The menu
software is simple and intuitive.
For a connection to a printer or a PC, a RS-232 or USB interface is build in
the device. The visualisation PC-Software NOVALOG MC for
Win9x/2000/NT/XP/Vista/Windows 7 is included in the delivery (except for
the “BASIC” version). A recorder can be connected to the 0…10 volt
analogue output.
