GEIGER COUNTERLUDLUM MODEL TWO
WITH SIDE-WINDOW PROBE
for detecting gamma, beta or alpha radiation
This Ludlum geiger counter works well, and
includes an end-window probe on a BNC cable.
This side-window probe is less sensitive
than pancake probes, but is
more sensitive than side-window
probes. This geiger
device uses one two standard D-cell batteries;
the batteries are effective for more than a
hundred hours of use
.
The manufacturer is Ludlum Measurements Co.
of
Sweetwater TX.
Ludlum is America's largest
manufacturer of geiger instruments, employing 600
staff. All Ludlum geiger
counters, and all their
components, are
made in USA. My wife and I
had a half-day tour of the Ludlum factory
during our visit in March 2018. The site is
very windy; the town is surrounded by
thousands of power-generating wind turbines.
BNC PROBE-SOCKET ALLOWS
USE OF WIDE VARIETY OF PROBES
THE END-WINDOW PROBE
is in perfect
operational condition.
As is true
with all geiger
probes
made in North America, this probe
operates
on DC 900 volts. With its BNC probe
socket,
the instrument is
versatile and can
use any type
of geiger probe
made
in North
America: pancake, end-
window,
side-window,
or scintillator probe.
FLASHING WHITE
LED LIGHT
On the left side of the bathtub
case, I have installed a bright
LED lamp which flashes in synchrony
with the loud clicks heard on the
speaker. Both flashes and sound
clicks can be turned off with the
audio switch on the top panel.
Extras will be enclosed,
such as several DVD disks,
photos of the uranium rock canyon,
published articles about uranium
mining, etc. The geiger counter
will be a good instrument either
for outdoor prospecting, or
for indoor use with your
uranium rock collection.
BONUS ADAPTER CABLE:
LUDLUM-C
SOCKET
TO BNC PLUG
Suppose that you already own a geiger probe,
and it has a Ludlum-C "male" plug.
No problem!
I have made a 12" adapter cable so that you can
use a Ludlum-C probe with this
geiger counter! Just
insert that probe's
plug into the "female"
C-socket on
this short
cable, then insert the cable's
gold-plated
BNC
plug into the socket of this Ludlum Two.
Of course,
you also have the side-window probe included with the
instrument. With
this adapter cable, you can use ALL
North American
geiger probes: those with
BNC plugs
plugs or those
with Ludlum "C" plugs. Total flexibility!
.00 DISCOUNT IF THIS GEIGER
COUNTER IS PURCHASED WITH
NO PROBE INCLUDED
The end-window probe is included with purchase
of this Ludlum Two instrument. If you already
own a working geiger probe, and do not need
another, then I will discount the total price by
.00.
Pancake probes are the most sensitive
type of probe.
The second most sensitive
type of probe
is an end-
window
probe
.
GEIGER COUNTER WILL
BE FULLY CALIBRATED
Prior to shipping, I will check and adjust the
instrument's calibration.
My calibration
tools
are: (1) Ludlum
Model 500 calibrator, (2)
Eberline
MP-2 pulse generator,
(3) Fluke high voltage DC
probe,
and (4) Sperry high-level DC
voltmeter.
Calibration involves
adjusting the three range-
multipliers, and also adjusting
the geiger's
DC-900 volt
signal that energizes the probe.
MAKE AMERICAN URANIUM
MINING GREAT AGAIN!
If fully developed, New Mexico's uranium
mines, closed since 1989, can supply 100%
of America's electric power for the next
250 years. The Mount Taylor Mine at
San Mateo NM, America's richest,
is planned to reopen in 2023.
BONUS 40-MINUTE DVD VIDEO,
NOT FOUND ON YOUTUBE!
Enclosed with the uranium rock will be
my original DVD video disk produced
during March 2017 and July 2019. This
40-
minute video provides a narrated tour of
the locale where these uranium rocks are
found through prospecting. You will see
Jurassic Canyon's Northwestern Cliffs, which
geologically exemplify the Morrison Formation.
The Morrison Formation
has been the source
for more than half of all uranium ore mined
in the past hundred years; It is also the
richest source of dinosaur fossils. The DVD
video program is enclosed at no extra cost.
(This DVD video is unavailable on
YouTube.

WHAT YOU GET FOR
0.00 PLUS SHIPPING:
1. Ludlum Model Two geiger counter
instrument in excellent working condition.
The glass meter has three scales: counts-
per-minute (CPM), mr/hr, and battery.
2. Three pounds of natural uranium rocks,
with 15% giving low-level response, 70%
giving middle-level of response, and
15% giving upper-level response.
3. A 6" Fiesta Ware dinner plate, 1936-1943
vintage, with 14% uranium glaze. The glaze
color
is d
escribed officially as
"radioactive red,"
but
its appearance has an orange hue. The
Fiesta plate's activity is
at a moderate level.
4. Many printed extras such as newspaper
articles, photos, brochures, etc.
5. Original 40-minute DVD video,
"JURASSIC
CANYON URANIUM,"
dated March 2017
and July 2019, showing details of the locale
where most of the three pounds of uranium rocks
were found. More than half of all uranium
ore mined in the USA in the past century has
been found within fifty miles of Jurassic Canyon.
(This DVD video is
not
displayed on YouTube.)
6. Two or more other DVD videos on
uranium-related topics. These may be about
the uranium mining industry, historical
topics, or atomic bomb tests of the 1940s
to 1960s (recently declassified films)
7. Two D-cell batteries in the
instrument, plus a second new pair.
8.
Photocopy of the user's manual for
the Ludlum Model Two geiger counter.
9. TWO BNC CABLES: One is short
(3 ft) and the other cable is long
(4-5 ft). Velcro straps are
enclosed so that the long cable can be
attached to the buyer's wooden pole;
this enables the prospector to test
uranium rocks on the ground without
having to bend over while doing it.
10. 12" BNC ADAPTER CABLE FOR PROBE
WITH LUDLUM "C" PLUG. This special
cable ensures that ANY geiger probe
made in North America, can be used
with your geiger counter.
11. THREE VINYL ROUND COVERS
TO PROTECT THE PROBE-SENSOR.
These can be either red color or
black color. The sensor inside the
probe is delicate and fragile, and
these vinyl covers protect the sensor
from damage.
12. FLAT URANIUM ROCK IS
ATTACHED TO RIGHT SIDE OF BATHTUB
CASE. A strong adhesive glue holds the flat-
sided rock to the case. The rock generates
25,000 CPM activity when measured with a
pancake; the end-window must be protected
with a vinyl cover that is provided.

NO CORROSION IN THE
BATTERY COMPARTMENT
Be wary of any geiger counter advert
that fails to show a closeup photo of the
battery chamber; Rust or corrosion
could make the instrument unusable.
This geiger counter instrument has
absolutely NO rust in the battery
chamber
and the instrument is
unaffected.

ROCK HOUNDS: FREE ESCORTED
ROCK-COLLECTING OUTING
Buy this geiger counter from me, and I can guide you
during uranium rock collecting: Either at Jurassic
Canyon (near Grants NM) or at Uravan Uranium
Fields, near Naturita Colorado. I will keep half
of the found rocks. Best months for rock
collecting are
April through November.
NATURAL URANIUM
ROCKS ENCLOSED
Possibly, dinosaurs may have
trampled on these uranium rocks.
These will total three pounds,
minimum. They will not be identical
to rocks shown in photos; They will
be a random assortment of
uraninite,
carnotite, tyuyaminite, coffinite, or
Jurassic todilto limestone.
The Jurassic
todilto limestone rocks have an age of
approximately 200-146 million years. The
northwestern cliffs at Jurassic Canyon
are part of the famed
Morrison Formation,
known both for uranium and also for
dinosaur fossils.
More dinosaur fossils,
and more uranium ore, have been recovered
at Morrison Formation sites than at any
other
geological sites in the USA.*
Some of
the enclosed rocks will be from the Lisbon
Valley
uranium region in Southeastern Utah,
where I prospected for the rocks, in June
2017.
Some will be from Uravan Colorado,
where I gathered uranium rocks in April 2018.
For shipping, the rocks are contained in metal
cans for shielding while being transported,
so I may need to swap in other rocks to
fit the space available in the containers.

SIXTY DAY MONEY-BACK
SATISFACTION WARRANTY
About half the geiger counters sold on
are advertised as, "Untested - No
Returns." I suspect that sellers who
advertise in this way are unloading
dysfunctional junk, and they know it. Why
buy from them? I offer the best money-
back
returns during the first sixty days.
You can return the instrument even if it
works
perfectly, but you expected
more features.
SHIPPING COST
Shipping will be via UPS-ground.
Any overpayment on shipping costs
will be fully refunded, immediately
after the parcel has been shipped.
The parcel will be insured by UPS.
