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.

    Recent exhibitions have been launch venues for key developments in aggregate production technologies - Mike Woof reports Efficient production of aggregates is crucial for maintaining cost-effectiveness and also lowering material costs. With contractors owning many of their own quarry operations, these firms understand the benefits of reducing materials costs for their road construction projects. Major developments in the equipment for crushing, screening and washing aggregates are now coming to market and e

    Machine control technologies are revolutionising construction – Dan Gilkes writes Electronic control of engines, transmissions and hydraulic systems, primarily to reduce exhaust emissions and boost productivity, is also providing manufacturers with an opportunity to incorporate increasingly complex machine control into their equipment. This in turn has the potential to make the machinery more productive, further cutting fuel consumption as part of a virtuous operational circle.

    Kevin Vine reports on the use of non-destructive testing for structural analysis of bridges Seven years ago, the overpass collapse in Laval, Québec that led to the death of five people brought to light severe issues with the state of the country’s bridges and transportation infrastructure. More recently, a crack in the Champlain Bridge to Montreal that forced over 160,000 commuters to find alternate routes to work reaffirmed a need for greater emphasis on early detection before a crisis occurs.
