How to lock android tablet for web browsing only?

Im developing a web app for some clients and Im going to lend then an android tablet (one of those cheap chinese non-brand tablets, pretty easy to manipulate) and Im kind of new into android so I want to know how can I lock all system apps (including settings) and leave them with google chrome enabled, even with a browsing lock that only allows to navigate in the desired domain. As a plus I would like to have like a remote monitoring of the tablet so I can see the activity. Im asking such an ambiguous way cause I dont know anything about android, but I imagine that this can be done because is such an open OS. If someone can recommend me some apps or website where I can get more info about this. Thanks!!
