Available with IntelliTouch or IntelliTouch Plus surface acoustic wave touchscreen technology or Acoustic Pulse Recognition (APR), the 2244L provides stable "drift-free" operation with outstanding image clarity, resolution, and light transmission for an accurate touch response and vivid images. APR is the recent ELO Touch Solutions innovation that supports touch activation by any stylus pen, glove, bare finger and fingernail, while IntelliTouch is the optical standard of touch and widely used in kiosk and gaming applications. Both are pure glass construction to deliver a clear, bright and long lasting performance and it also makes the touchscreens scratch resistant. It is nearly impossible to physically "wear out" these touchscreens.
