Sorry, this item is out of stock
LTL2000 RETROMETER, On site quality control of road markings & road surfaces in agreement with CEN specifications
The LTL2000 Retrometer is a self-contained, portable instrument with built - in facilities, capable to measure accurately and reliably retroreflection properties of road surfaces and road markings (dry and wet) including those with profiled and/or textured surfaces.
The LTL2000 Retrometer measures the retroreflection (with direct read-out of the coefficient of retroreflected luminance in mcd-m-2 .lx-1) at a simulated distance of 30m, a distance large enough to be relevant for practical driving conditions at night.
Built-in printer and non-volatile memory provide registration of measurement results and corresponding supplementary data. Serial interface RS232 is included for extended control, calibration, and data output. The LTL2000 Retrometer is powered by a rechargeable battery with a capacity corresponding to approx. 1000 measurements . A mains powered battery charger is supplied as a standard accessory.
