STB150B 4+

This app is only functional in conjunction with the drawbar scale STB 150B from AT SensoTec, which can be purchased here: https://atsensotec-shop.de/

We have developed this digital drawbar scale so you can monitor the current towball weight of your trailer or caravan while loading it.

This app makes it possible to comfortably read the current towball weight on your iPhone.

In order to measure the towball weight the drawbar scale has to be attached into the towball coupling. Sensors calculate the force which acts on the towball coupling. This allows the towball weight to be monitored while loading the trailer or towing vehicle.
