SUPERIOR'S NEW MODEL 80
Compare it to any peak -to -peak V. T. V. M. made
by any other manufacturer at any price!
Uses new Improved SICO printed circuitry.
Employs a 12AU7 as D.C. amplifier and
two 9006's as peak -to-peak voltage rectifiers
to assure maximum stability Meter Is isolated
from the measuring circuit by a balanced
push -pull amplifier. Uses selected
cero temperature coefficient resistors as
multipliers.
AS A DC VOLTMETER: The Model 77 is indispensable
in HI -Fi Amplifier servicing and
a must for Black and White and color TV
Receiver servicing where circuit loading cannot
43e tolerated.
AS AN ELECTRONIC OHMMETER: Because
of its wide range of measurement
leaky capacitors show up glaringly. Because
of its sensitivity and low loading,
Intermittents are easily found, isolated
and repaired.
AS AN AC VOLTMETER:
Measures RMS value If sine
wave, and peak -to -peak value
If complex wave. Pedestal voltages
that determine the "black"
level In TV receivers are easily
read.
Comes complete with operating
instructions, probe leads, and
steamlined carrying case. Opvolt

large easy -to-read calibrations No squinting
or guessing when you use Model 80.
so MIRRORED SCALE permits fine accurate
measurements where fractional readings
are important.
so CAPACITY RANGES permit you to accurately
measure ll condensers from
.00025 MFD to 30 MFD in addition to the
standard volt, current, resistance and
decibel ranges.
so HANDSOME SADDLE- STITCHED CAR-
RYING CASE included with Model 80
Allmeter at no extra charge enables you
to use this fine instrument on outside
calls as well as on the bench In your shop.

A built -in Isolation Transformer
automatically isolates the Model 80
from the power line when capacity
service is in use.
Selected, Ir: zero temperature coefficient
metalized resistors are used
as multipliers to assure unchanging
accurate readings on all ranges.

Nothing else to buy. Only
Endless experiments and discoveries In the
new
field of nuclear energy are
made exciting possible when you acquire this finely
built and engineered device. In the past. a
rugged counter which was suitable for the
prospecting of radio- active ores such as uraium,
thorium and radium, was unsuitable
for laboratory work due to the inability of
combining accuracy with ruggedness. Conversely
a laboratory counter, while being extremely
sensitive, could not withstand use in
the field where it would be subjected to abuse
and abnormally hard knocks.
In the laboratory where determination of
intensity (counts) of a reading are necessary,
the WF -11AWR provides sensitivity for surpassing
many laboratory counters.
