Road Pavement Protruding Signs Mark Retroreflectometer

The LS-201C is an instrument designed to measure the primary performance indicator of road pavement Protruding Signs Mark – the coefficient of luminous intensity. It operates on a Windows CE-based control platform and is equipped with a 32-bit high-speed processor core, providing a user-friendly and practical human-machine interaction interface. This instrument is ideal for use in photometric laboratories, testing centers, and highway construction sites. It is also suitable for quality inspection of Road Pavement Protruding Signs Mark by manufacturing plants. The instrument is specifically designed for measuring rectangular Road Pavement Protruding Signs Mark.
