The device hardware can be taken apart into three component blocks that can easily be lifted by one person and transported in any passenger car. At the test site, the operator swiftly reassembles these three blocks in a few simple steps. When put together, the ZORN Asphalt Tester does not require a separate trolley or similar device for transport on site. The operator simply rolls the device comfortably between measuring points on large, integrated wheels. Once there, the drop weight section is moved from transport into the measuring position with a click and testing can begin.

The ZORN Asphalt Tester is controlled wirelessly by means of a tablet computer. The tablet computer is connected to the sensors of the tester via Bluetooth (acceleration & temperature). The easy-to-use control software also offers the possibility to seamlessly create test reports and send them to co-workers or clients online. ZORN Asphalt Tester - consistently digital and connected!
