LTL–XL is the professional choice for measuring the retroreflectivity of road markings.

LTL–XL measures all types of road markings at a simulated distance of 30 m with the highest level of accuracy. The instruments operate with a reproducibility of +/- 5% and a repeatability of +/- 2%.

LTL–XL measures, depending on the model chosen, RL (nighttime visibility), Qd (daytime visibility), visibility under dry, wet and continuous rain conditions.

LTL–XL is robust, long lasting and advanced instrument designed for professionals using the latest developments in light and sensor technology. Using DELTA’s gradient index technology and patented optical system, the instrument can measure all types of flat and profiled markings. The sensor response, combining the CIE eye response and the CIE illuminant A, meets both CEN and ASTM requirements for profile capacity and colour.

LTL–XL measures white and yellow markings with no adjustment. LTL–XL has automatic stray light compensation so daylight and other light sources will not affect the accuracy of the measurements.
