ELO touch pen caps, replacement caps for touch pen systems for capacitive and resistive Input aids facilitate operation and input in difficult environments. Especially when working with gloves, touch pens can often be very helpful when operating touch displays. Despite wearing gloves, you can operate small buttons or input fields with pinpoint accuracy. Touch pens also protect the display against dirt and scratches during operation and when operating in extreme environments. When ordering, pay attention to the touch system (resistive or capacitive).
