SY Road Marking material Reflection Tester is special optical measurement instruments. There are Reflection coefficient R' and Unit mcd·lx -1 ·m -2 displayed. It is easy operation and result valuable .It can either be used in laboratory, or be used in site for producing, quality monitoring, projects, Measurements and university demo. Main specification:
Light source color temperature: 2856K (CIE A source.)
Detector is silicone diode + V(λ)corrector and after correct by light filter that apply with CIE standard.
Measuring range(R'): 0~1999 mcd·lx-1·m-2.
Principle graphic
Introduction: It composes of part 1.console (include: light resource, optic system, detector, amplifier and display.) And part 2.accessories (include recharger, zero board, calibration board.)
Operation:
Zero setting
After full charge, turn 7 (Function switch) to test mode and turn on 2(display switch). Put the bottom open at the (300mm*600mm) black zero board and press test button (5). Now the value on display is 0. If not, turn zero buttons until to zero.
Calibration:
Take off zero board and change calibration board according to moving direction on it. The value on display should be the same as the value on calibration. If not, turn calibration button (4) until the same.
Testing:
After zero setting and calibration and then start test. When testing, keep it flat according to driving direction and press test button (5). Preheat one minute after shows stability value, that is the (R').After testing, turn off test button on time. When all tests are finish, turn off LCD switch (2), and function button to middle place.
