Danish company 199 Delta is introducing its new RetroSign GR3 Retroreflectometer for quality control and asset management of road signs and retroreflective materials with laboratory precision.

The company says that to achieve these goals the triple geometry retroreflectometer is offered with GPS and RFID (radio frequency identification) reader.

The handheld instrument is used for measuring the retroreflection of traffic signs. It measures the coefficient of retroreflection (RA) according to US and European standards.

"The triple geometry facilitates simultaneous measurements at various observation angles as proposed by ASTM (The 3930 American Society for Testing and Materials). The RetroSign GR3 measures simultaneously at observation angles at 0.2/0.33º, 0.5º, and 1º," says DELTA.

"The point aperture geometry specified by ASTM ensures realistic and accurate readings replicating realistic driving conditions. Furthermore it enables the user to determine if a microprismatic sign sheeting material has been applied correctly.

Due to the DELTA proprietary gradient index ultra hard coating (UHC) technology the sensor response meets the ASTM 1709 requirements combining the CIE (International Commission on Illumination) eye response and CIE illuminant A." DELTA says that the RetroSign GR3 is designed to easily interface with current and future ID tagging and asset management systems, and the internal memory stores up to 250,000 readings, "which essentially means that the instrument never runs out of memory."

    Sophisticated on-board weighing systems for use with wheeled loaders and excavators are being offered by Loup Electronics. The innovative LOADEX 100 is a retrofittable scale installed on tracked and wheeled excavators and material handlers to weigh the amount of material load in the bucket or grab. Pressure signals are captured, filtered and corrected by measuring the angle of the main boom using either an RDS Inclinometer or Mechanical Angle sensor. When used dynamically, the pressures are captured through

Congestion (and how to relieve it), along with safety, are among the top priorities facing those responsible for looking after the UK's roads. Road pricing, car-share lanes, greener vehicle initiatives and alternative methods of transport such as buses, trams and rail are all part of the approach, but prior to the current economic climate the nation's love affair with the c
