Horizontal Classic is a robust, simple and intuitive handling instrument which can simultaneously evaluate nighttime visibility (RL), daytime visibility (Qd) and register the ambient temperature and relative air humidity fast quickly, easily and effortlessly.
Horizontal Classic complies with all international standards for road marking: EN 1436 (RL and Qd), ASTM E1710 (RL), ASTM E2177 (RL wet) and ASTM E2302.
Optionally the classic horizontal retroreflectometer can implement two true-optical patches (independently) to check 15-meter and 30-meter geometry at the a single button press. This unique feature allows checking results in dual geometry precisely and effortlessly
