Keith:

The information on the equipment is as follows:

Model 16        Purchased new 7-8 years ago.  Used only for training demos
and classroom lectures.  Not calibrated in last year.  Current price from
Ludlum is $580.  I am asking $350.

Model 177       About 10 - 12 years old, new GEL cell and fast charger
accessory 2 years ago.  Ludlums new price is $575, I am asking $300

Model 2200      One of the original 2200 units made by ludlum, this unit was
returned to the factory about 4 years ago for replacement of the display
elements with the modern large LEDs, electronic evaluation, and calibration.
The only defect I know about is the leather & padding is missing from the
handle.  The current Ludlum catalog is $1425, I am asking $750.

Model 44-3       about 10 years old, and the XTAL is 1" diameter by 1mm
thick.  It is best for Iodine and XRD/XRF work.  When last calibrated to a
129I source it showed about 6.5% Efficiency.  Ludlum's price is $370, I am
asking $100.

TA Pancake GM   About 15 years old.  New GM tube about 2 years ago.
Anodized aluminum case with lead shield on back/sides of tube.  Last
calibration was ~4.5%E for 14C.  Asking $100.

Radiation Alert Model 4, about 6 years old.  "pocket" miniature mr/hr GM
counter with spare tube.  Very linear response when last calibrated.  Asking
$150.

Spares/Cables   Include new Ludlum model 2/3 mother board, 2 BNC to C
adapters, 2 BNC cables (18", 72"), 40 inch C cable.  Ludlum meter bezel,
glass, and 202-330 meter face.  Asking $150.

 I am selling the equipment because I had to take a disability retirement
last year, and can not work in a chemical/laboratory environment.
Therefore,  I have not calibrated or used them in the last year, and have no
means of determining the current efficiency of the detectors.  I have
checked the electronics with a GM probe against a lantern mantle, and they
seem OK.  If you are interested, any sale would of course be contingent on
the equipment operating in a satisfactory manner, and does not include
shipping/insurance.  Thanks for your inquiry.
