LTL-X Mark II

Excellence in measurements

Made-to-excellence in measurement, the LTL-X has become a genuine success in the market. It outperforms other makes of handheld retroreflectometers for pavement markings in relation to measurements of night visibility (RL), incl. handling of white and yellow markings with no adjustments. In addition, the LTL-X lends itself well to measurements of high profiled markings up to 15 mm (0.6 inch).

Developed to meet the requirements of the North American market under “dry”, “wet” and not least “continuous wetting” conditions, the LTL-X has basically become a de facto standard for handheld measurements in this market as well as in several markets in Asia and Central & South America.

LTL-X Mark II

LTL-X Mark II is an upgraded model

of LTL-X with several new features like clearly visible color LED screen, large memory capacity of 200.000 measurements,  recording of temperature and relative humidity and a simple one-step calibration process. It still has the unique features of LTL-X measuring retroreflection under continuous wetting, high profile marking measurement capability and fast measurement time of 1 sec.

Easy-to-use

An intuitive user interface, easily handled also when you wear gloves, fast and accurate acquisitions, GPS supported measurements and a built–in printer offer optimum working conditions. Measurements will be displayed, and printed instantly if needed. Data acquired can fast and seamless be uploaded to a PC for further analysis through a USB connection. Road Sensor Control (RSC) software is supplied with the instrument,

and analysis support functions include transfer of data to e.g. Google Earth, which offers excellent overview of acquired data referenced to the exact measurement positions.

High performance – and many measurements

The LTL-X Mark II is a rugged instrument offering good ergonomic working conditions, including adjustable handle height for the operator, and in addition wheels. The performance of the instrument is high, its repeatability is better than +/- 2% and reproducibility better than +/-5%. Typically over 2500 measurements can be obtained per battery charge, thus eliminating downtime. LTL-X Mark II comes with two reference/calibration tiles, one for use in the field and one for storing in the company as the calibration tile. The latter is calibrated by DELTA’s accredited photometric lab, which has direct traceability to NIST & PTB.
