Standard deviation of error is less than 0.080 in. (2.03
mm). Equates to less than ±1%.
More than 100,000 touch points/in2 (15,500 touch
points/cm2).
Typically less than 3 ounces (85 grams).
Surface durability is that of glass, Mohs' hardness rating
of 7.
No known wear-out mechanism, as there are no layers,
coatings, or moving parts. IntelliTouch technology has
been operationally tested to more than 50 million
touches in one location without failure, using a stylus
similar to a finger.
Unit is sealed to protect against splashed liquids, dirt,
and dust.
