The sign retroreflectometer is an instrument for measuring the photometric performance (retroreflective coefficient) of retroreflective materials, the unit: cd·lx-1·m-2. It can be used for traffic safety management and highway, railway, aviation and other related departments to conduct on-site measurement of retroreflective signs, etc., and can also be used to measure the reflective performance of reflective signs on trucks and motor vehicles, and to monitor the reflective quality of production retroreflective materials , to ensure that the retroreflective marking materials meet the requirements of the relevant standards.

This model is single angle which has only one observation angle. If you need multi-angle version, pls refer to our model TBTTSR-1M.
