12V towing vehicle tester, test device for 13-pin trailer sockets, CAN bus compatible

The ZWT 50 (12 V) towing vehicle tester is a professional lighting tester for checking 13-pin trailer sockets on towing vehicles. Thanks to its 5 m connection cable, the entire test can be conveniently carried out from the driver's seat – by just one person. Ideal for automotive workshops for quick functional testing and reproducible diagnostics in everyday workshop operations.

Your advantages in the workshop
