For examiners considering pre-owned equipment, our refurbished polygraph equipment buyer's guide provides valuable guidance.

Factors to Consider When Selecting a System

When evaluating the Axciton CPS against other professional systems, examiners should consider several factors: agency or employer requirements (some agencies mandate specific manufacturers), compatibility with validated examination formats, scoring algorithm availability, training and support infrastructure, and long-term total cost of ownership including software updates and sensor replacements.

The Axciton CPS offers several compelling advantages: it is the only system from a fully independent manufacturer, it provides proprietary algorithms (STAR, WhiteStar) alongside universal tools (PolyScore), it features a unique hybrid EDA recording approach, and it delivers direct manufacturer support. The system's modular design — from 4 to 24 channels [14]Verified Axciton Polygraph Distributor — Technical Specifications
