The CANtouch is a handheld, battery-powered diagnostic tool for physical as well logical analysis of CANbus systems. With its modern touch controls, it allows intuitive, efficient handling without an additional computer.
As a follow-up to the CANbus Tester 2, it doesn't only feature its predecessor's functionality, but it has new additional measurement capabilities. The analyser provides a quick overview of your network's health via a mix of traffic lights and smileys. It has an integrated update capability which allows further enhancements. New functionalities can be unlocked by purchasing additional licenses.
