Free Advanced Product Training for Customers!

For limited period only, if you purchase 4 or more sets, we will provide a free 2-day on-site hands-on advanced product training on the LX6-S and LX5000. The objective of this training is to learn how to exploit some of the powerful features of the LX Software on digitisation to increase efficiency, go paperless and facilitate digital archiving and retrieval. Some of these advanced topics are not normally covered in any polygraph courses or seminars because they require IT knowledge. The advanced topics include internal LX Software file structures and customisation of internal polygraph records, reports and templates to suit each department's needs. The default formats were designed for certain US customers.

Another important topic covered in the 2-day course will be hands-on training on the calibration of the LX6-S and LX5000. This part of the training will be most useful for examiners who lack knowledge in this area. Customers are encouraged to purchase the Lafayette Functionality Check Device 76740LX.

LAFAYETTE LX4000-SW Accessories

Lafayette has ceased production of the LX4000-SW in 2018. Without a doubt, the Lafayette LX4000-SW has been a favourite with many polygraph examiners and have contributed to many good results. However, it has reached end-of-life and Lafayette has offered generous trade-in for a state-of-the-art model. You are encouraged to upgrade. Contact us for a quote. For folks who continue to use it, the good news is that the accessories for the LX4000-SW are still available for purchase.

US Export Licence

The U.S. Department of Commerce requires an export licence for any polygraph system shipment to certain countries. It is against U.S. law to ship a polygraph system to these countries without an export licence. Contact us for the required licence application form. This is a simple and standard procedure, and we will be happy to assist you in completing the forms and we will do the rest.
