Polygraph Test – Lie Detector Test, What Is The Difference?
Polygraph testSo what is a polygraph test when we hear lie detector test, what is the difference? There actually isn’t any differences. Polygraph stands for many lines as seen on a polygraph chart when someone is tested. In the UK, we refer to the polygraph as a lie detector. They are both exactly the same thing just different terminology for different markets, clients will often ask us if there is any difference. John Larson invented the polygraph test in 1921 with further work by Leonard Keeler, in 1939 it was adopted by the FBI who still to this day are one of the world’s biggest users of polygraph tests. To this day law enforcement and intelligence agencies worldwide rely on polygraph tests. There are three main polygraph manufacturers today, Stoelting, Lafayette, and Limestone. All do a very similar job to the same accuracy levels, and are made in the USA. Different examiners prefer different machines. We at Lie Detectors UK use Stoelting devices as the majority of the latest research has been done using a CPS Pro polygraph hence our choice of polygraph. In the last ten years most examiners have upgraded to a fully computerized device, in fact we know of no qualified examiners in the UK using an old analog polygraph which is a good thing as they aren’t as accurate. When choosing who to run a polygraph test make sure they are a member of the British Polygraph Association as this not only shows they are fully qualified but also that they are using the latest polygraph equipment and have been trained to the latest standards making your polygraph test as accurate as it can be.

They also cover the UK and are able to travel to you and test in a home if it’s a distraction free environment or hire an office close to you. More information on wikipedia
