The TOUCHSTONE
(see operating instructions)

The TOUCHSTONE electronic muscle tester is an microprocessor-controlled adaptation of the 'arm pressure test' as employed by chiropractors, psychologists and complementary health practitioners across the world, to measure a body's response to foods, products and the subconscious.  The sensor for the TOUCHSTONE was developed for us by Sensitronics , the leading experts in the field.  (click here to see a more technical overview)

The TOUCHSTONE'S patented software compares the strength of finger pressure readings, adjusting for different rates of acceleration, and then shows through a series of 'green,' 'red,' or 'amber' lights whether a substance or thought is potentially beneficial, detrimental or neutral.
