DELTA Roadsensors is the globally leading supplier of retroreflectometers. DELTA offer two existing lines of products: the LTL line for measuring retroreflection of road markings and the RetroSign line for measuring retroreflection of road signs.

Well-known instruments

DELTA's instruments are known in the market since the 70es and are recognised for their accurate measurements and for being robust instruments.

The recent generation of instruments, RetroSign GR1, RetroSign GR3, LTL-X and LTL-XL, are very user friendly when it comes to instrument form and weight, calibration of the instrument and setting up the instrument for measurement.

Transferring measurement date to a PC via USB interface or Bluetooth is the standard.
