SPECTRON 300E LEAK DETECTOR
FEATURES
Edwards Spectron 300E portable makes
possible fast, effective leak detection over
the range atmosphere to
without liquid nitrogen.
Together with the lightweight hand-held
module, the Spectron 300E represents a
simple to use, readily portable and reliable
industrial wide range leak detector.

DOUBLE PUMP SYSTEM
PORTABILITY
The Spectron 300E employs a unique double diffusion
pump system for high performance combined with
rugged reliability. One of the Edwards E040 air
cooled diffusion pumps continuously pumps the mass
spectrometer head via a special restrictor. The other
pumps the test piece. The high compression ratio
acheived gives a fast response and a very fast clean-up
time unaffected by helium in the backing line. In
addition the sensitivity of the Spectron 300E is
independent of the size of backing pump used.
PROCESS CONTROL MODULE
The system is simple to use at any
desired level of control, with
facilities to prevent tampering, which
is particularly important for a
portable instrument.
The unit has an alpha-numeric LED
display for clear viewing at a distance
and there is a standard recorder
output to enable a permanent record
to be made.
keylock
The Spectron 300E is a strong rugged leak detector
designed to operate in dirty industrial conditions as
well as the clean research areas.
Spectron 300E features fold down carrying handles
but for those applications where the unit is likely to
be in demand over a large site a specially designed
trolley accessory is available. The trolley runs easily
on large go anywhere wheels and features a handy
lockable storage space for instruments, accessories
and tools.
UNPARALLELED RANGE
The Edwards 300E is a complete unit
which gives the best specification
without having to buy extras.
The massive, gross and fine test
modes, all built into the unit, cover a
range of atmosphere to
and the maximum intake pressure
is one atmosphere. The minimum
detectable leak rate is unaffected by
the size of the backing pump. Clean-
up time and stability are superior to
other units.
A larger roughing pump can be fitted to tne trolley
rapid evacuation of larger volumes. Alternatively, the
pump can be bench mounted and connected via a side
port on the leak detector. This will not affect the
sensitivity.

SINGLE HANDED LEAK
DETECTION
The hand-held control
module has been designed
to be as small as possible
yet give all the
information and control
an operator will need as
far away as 25m from the
leak detector.
Edwards has also designed
a visco probe, which can
be fitted to the hand-held
control module if
required enabling single
handed leak detection.
The visco probe is pumped by the E2M1.5 backing pump
interstage so there is no need for a costly auxiliary pump.
The hand-held control module features a linear 50
segment bar graph readout of leak rate with exponent
for at a glance leak detection. The module will give an
indication of valid test mode and there are four controls
for manual/auto ranging and zeroing. There is also a
socket for headphones for the audio output when
hand module can be attached to the
vacuum module so that its display/
controls conveniently complement
on the front panel.
RECORDING
A data logger can be connected to
the RS232 port. Alternatively the
Spectron 300E can be operated
remotely, through the RS232 port, by
a computer/PLC or a modem.
SERVICEAND MAINTENANCE
Thanks to the well thought out and
easily accessible interior, the Spectron
300E is simpler, easier and less costly to
maintain than many other portable leak
detector units. The mass spectrometer head will require
little maintenane since it is kept clean by use of special
techniques to reduce the contaminants entering in the mass
spectrometer chamber.
STABILITY
The unit is fitted with a stabilised power supply, which
means that the pumps always operate at optimum
performance.
