The 709CNH offers all of the innovation and inputs as our 700 series models along with a Capacitive touchscreen panel. Capacitive sensing provides a more responsive touch interface than resistive touch. It achieves this by using the capacitance of human skin to detect the proximity or position of the input. Proximity sensing allows the touch interaction to work even if protective glass or coating is used over the display. The IP65 rating on the display provides for protection against solid objects and liquids. This display is guaranteed to prevent any amount of dust from entering the device, making it completely dust proof. Further, it is guaranteed to protect from water projected from a nozzle from having any harmful effect.
