There is no specific OV-chipkaart for tourists. They can use an anonymous or disposable OV-chipkaart:

• The anonymous OV-chipkaart is a plastic card on which an amount or a travel product can been loaded. 
• A disposable OV-chipkaart for one trip or for a predetermined short-term use. For example, a one-day train or bus ticket or a 3-day ticket for all public transport within the city of Amsterdam.
