My name is Mike Kelly and I have an old analog polygraph instrument I have for sale. 
As I mentioned on the phone, I have NO idea of what this is worth.  At the end of the day, obviously only what someone is willing to pay.  That said, I think I'd like to put it out there for $375 - I can't imagine it isn't worth more than that.
SO, all I know is what I see - this is a Lafayette Instruments "Diplomat DC III" analog instrument.  I believe it is a mid-80's vintage.  I am told it is complete with all accessories and works well.  The only issue it has is a need of battery replacement, but the unit works fine on AC power.
Over to you to elaborate and post however you wish.  You can include my name, email address ([email protected]) and phone number (703-554-3277) as a POC on this.

 

Like New Lafayette LX-4000 Polygraph Instrument with both pneumos, EDA wire with finger plates and hand pads (electro-dermal gel as well), blood pressure cuff and bulb, seat movement sensor, Brother Printer with three rolls of chart paper, webcam with desktop tripod and arm mount.   Asking $4,700 OBO.  If interested, please contact Ken Stauff, [email protected] 

 

 

 

 

 

Working Analog Polygraph Wanted
I am looking for an analog instrument for a film/tv prop work, not for real a test. I am based in the U.K. and would cover the shipping costs on top of the purchase price.
