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), 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.

    Five buoy-mounted automatic water quality monitors (AWQMs) have been installed by YSI Hydrodata engineers at the new Tyne Tunnel project in north-east England. The equipment on the second vehicle tunnel under the River Tyne, currently one of the UK's largest construction projects, aims to ensure that construction operations do not significantly affect river water quality. Unusually, the contractors have not taken ownership of the instrumentation, preferring instead to simply purchase the data and alarms. Th
