Normally when a passenger comes to the counter there is a scale that the desk clerk can weigh your bag. However, if you are looking for a scale other than this one, you will not find it. Per TTN airport, Frontier will weigh your bag at the counter. You may want to ask before check in starts, if they can kindly weigh your bag.
Most probably no but not sure if they installed it in last month..
