TBTTSR-1N Retroreflectometer is a portable, rechargeable battery-powered precision measuring instrument for the determination of night visibility (coefficient of retroreflection RA and R’) of traffic signs and safety garments.
Asphalt Non-Nuclear Electrical Density Gauge (EDG)
Asphalt Non-Nuclear Electrical Density Gauge (EDG)
TBTEDG-1A Non-Nuclear Asphalt Density Gauge is a portable non-destructive pavement quality indicator. It is mainly used to read the density of asphalt materials in new pavement(include upper, middle and lower layers of pavement structure layer). It is also suitable for old asphalt pavement with no pollution, smooth surface and loose surface.
Traffic Sign Retroreflectometer
Traffic Sign Retroreflectometer
This sign retroreflectometer is an instrument for measuring the photometric performance (retroreflective coefficient) of retroreflective materials. The Observation angle is 0.2°, entrance angle is -4°.
Road Marking Retroreflectometer
Road Marking Retroreflectometer
TBTRMR-1 marking retroreflectometer is a portable on-site measuring instrument, used for measuring the retroreflection characteristic of road marking. TBTRMR-1 type instrument is to simulate the brightness of road marking that can be seen by the driver under the illumination of motor vehicles at night, and the measured parameter is the coefficient of retrorefection brightness at night, namely, RL value.
