Handheld Instruments: StripeMaster II

For comprehensive pavement-marking measurement capability, including a built-in GPS and printer, consider the StripeMaster II. The StripeMaster II measures retroreflectivity of pavement markings per ASTM E1710 and EN 1436 30-meter geometry. Providing accurate measurements on wet (per ASTM E2176 and ASTM E2177) or dry surfaces, the lightweight StripeMaster II has an RS-232C interface that allows data to be downloaded into any traffic inventory system.

The StripeMaster II is designed for quick and easy measurements with the touch of a button. This lightweight instrument comes with wheels to make the measurement process a breeze. An internal GPS and printer come standard, allowing the field user to quickly verify the data.

The internal memory will store up to 10,000 measurements before downloading to a computer. The data transfer is simple with our datalogging software. The StripeMaster II connects to any standard computer using an RS-232C interface. Our mapping software allows the user to plot the data on a clickable and printable map to quickly identify problem areas that need attention.

Microprocessor-controlled calibration, with internal GPS and printer, makes the StripeMaster II the finest instrument of its kind in the industry.
