The LTL-XL from DELTA: built in modules

Box International studies have proven that relatively more accidents and fatalities happen during night-time driving compared to day-time driving.

At the end of 2008, Danish company 199 Delta launched its latest model, the LTL-XL, a fourth generation portable retrometer for measuring night and day-time visibility of all types of road markings.

"Measures are traceable to PTB (3998 Physikalisch-Technische Bundesanstalt), Germany and NIST (National Institute of Standards and Technology), USA. LTL-XL measures according to the international standards EN1436 and ASTM E-1710," says DELTA.

Its LTL-XL offers several new features compared to previous instruments from DELTA and these include the measuring of the ambient temperature and humidity; geotagging using GPS mapping software; USB connectivity and seamless connection to any system using a Web browser.

The new equipment is offered with a new coloured display, single-handed operation and single touch controls, which makes the operator's work much easier.

Using LED technology, which makes the instrument almost maintenance free, LTL-XL allows users to work efficiently with measuring times of 1-3 seconds and a large memory of more than 200,000 measurements.

"LTL-XL is built in modules to allow the operator to design the instrument according to actual needs. It comes in a base model to which can be added wheels and telescopic handle, GPS and printer," says DELTA.
