The LTSTP has been developed to test cargo x-ray screening systems with large tunnel sizes of up to 1800mm high.

It is essentially two STPs in a purpose made case that has been designed to sit directly on the x-ray machine’s rollers.

A solid base serves to reduce vibration and together with an improved method of AWG wire retention, the LTSTP will show an operator a clearer definition of images on the screening monitor.
