Roller Brake Tester LDV

RHO-8 (RHO-6/L(-A)) is a modern brake tester for vehicles with total weight up to 3.5 t including cars and delivery trucks, motorcycles/motorbikes, agricultural tractors, trailers and vehicles with 4 × 4 drive. RHO-8 might work as an element of an integrated UNILINE QUANTUM 2000 test lane or as an independent device.

The electromechanical part of the device is a proven design of high durability. All our devices are enhanced by innovative measuring systems and microprocessor control board, which work with the UNILINE QUANTUM software.

The user-friendly software guides users through the testing process and automatically interprets test results. The system has many additional functionalities, which might be activated when more advanced tests and analysis of brake systems are required.
