Vacuum gauge DVR 5
 The
new vacuubrand vacuum gauge DVR 5 with separate gauge head, serial
interface and an extended measuring range of 0.1 - 1100 mbar offers
analogue display and digital precision for clear trend indication
and precise read out. The separate gauge head with aluminia ceramics
transducer with high corrosion resistance is made for excellent
long-time stability, on the spot measuring and network capability.
The gauge head is direct mounted to proper spot of vacuum system
and pressure read out is at a convenient location.
Data transfer is via serial interface. The extended measuring range
contains furthermore user selectable units (mbar, Torr, hPa), electronic
scale conversion, digital calibration at atmosphere and vacuum and
pressure display over four decades. The new DVR 5 is safe and environmental
friendly : conformity with EC low voltage and EMC directive for
classification A and B requirements; no mercury, no sensitive mechanical
components.
Chemistry
vacuum systems PC 500/PC 600
 The
chemistry vacuum system is the ideal solution for many applications
and is perfect for use in all areas where flexibility and variability
are required. It is easy to use and environmental friendly and it
offers oil free vacuum and solvent recovery in vacuum generation.
The heart of the new chemistry vacuum system PC 500 and PC 600 is
a powerful vacuubrand diaphragm pump with particular advantages
and they don’t consume water. Modern intrinsically corrosion
resistant diaphragm pumps are using PTEFE-compound materials for
parts coming in contact with vapours and gages. The chemistry vacuum
system offers an ‘‘intelligent’’ vacuum controller
and an exhaust waste vapour condenser for next to 100 per cent solvent
recovery. The new vacuum system is compact, space saving and offers
access to all components. The vacuubrand laboratory pumping units
PC 500 and PC 600, designed especially for chemistry labs, generate
totally oil free vacuum, maintain predetermined vacuum and control
exhaust vapour emission. Solvent recovery is the ruling factor for
the choice of vacuum systems in chemistry. The variable and flexible
modular chemistry vacuum system offers the ultimate in technology,
economy, pollution control and performance for many applications
in chemistry labs. The new vacuum systems offer the possibility
to operate simultaneously several works stations with one vacuum
pump.
The pumping unit components are made of chemical- resistance materials.
The vacuum controller CVC 2 provides easy determination and reliable
control of desired or required process pressure, remote controlled
air admittance valve, permanent reading of actual pressure and three
operating modes (manual and semi-automatic).
Pirani
vacuum gauge VAP 5
 Pirani
all electrical vacuum gauge are not new, but they never succeeded
to replace popular mercury gauges entirely. Now with the new Pirani-
vacuum gauge VAP-5, vacuubrand has developed a vacuum gauge which
will help to get rid of mercury vacuum gauges in the fine vacuum
range.
The vacuum gauge VAP 5 works by the Pirani- principle of thermal
conductivity and is consequently a compelling alternative for all
vacuum gauges which still work by the mercury which is not harmful
to the environment.
Its main feature is its display : analogue trend easy to read at
quick glance display and a digital display for precise read out.
The calibration can be changed just by toggling through. The display
range of the new vacuum gauge is from atmosphere to 10-3 mbar with
proper reaching beginning at 100 mbar. The VAP 5 is a desk top unit
but also comes to a support holding device.
