We at Keiser realize that research is very important to the improvement to all areas of our society. A long history of Keiser research equipment initially began with groundbreaking Air 400. Since then Keiser has improved on the design and technology and produced the new Air 420 Research Grade Equipment. These machines feature high fidelity electronics added on the AIR250, AIR300 and AIR350 lines that allow researchers to accurately measure power, work, force and velocity.
The Keiser A420 is the latest in a series of exercise machines developed for the purpose of research. This series differs from its predecessors in many ways. It is designed to produce accurate position, velocity, power, and acceleration information throughout the exercise range of motion. This power is then mapped graphically on the embedded microcomputer for comparison and reference. Its predecessors, the A400 and A410, measure power as an average over an entire exercise repetition, whereas the A420 is capable of measuring power and velocity at any instant throughout the range of motion.
The A420 is fully compatible with the Keiser Chip System and can share data with it. The A420 series is designed to be easily ported to any existing Keiser Chip System machine. The PC shipped with the new Air 420 models includes a CD writer to provide for an easy way to archive collected data or send samples back to the factory for analysis when a problem occurs.
