The MINI retroreflectometer instrument has an external light beam.
That is,the light shines out of the instrument housing and on to the roadway away from the instrument. The external beam instruments are useful for the measurement of the wet condition.

The external beam instrument is essential for measuring retroreflectivity in the falling rain condition ASTM E2832.

Here a spray of water is directed over the subject section of road during measurementand this is only practicably possible with an open beam retroreflectometer like the new MINI for road markings.

It is time to leave the large and heavy traditional retroreflectometers behind.

The MINI Retroreflectometer for road markings is convenient and smaller.

With space aboard striping trucks at a premium , the MINI takes up much less
space.

For those staff who have to carry around and use the Retroreflectometer,
the strain on the arms and legs with the MINI is significantly reduced.

Street markings and legends are vital for moving traffic safely and efficiently on city streets. How visible is it at night ?

The MINI retroreflectometer  improve the inspection on city centers.

The technology miniaturization allows taking the equipment on the train or metro
– a challenging task for users of traditional models –
and offers valuable technical solutions, such as an external light beam and the
use of standard AA rechargeable batteries, which are safe and easy to replace.

The MINI Vertical is an up to four angle retroreflectometer designed to accurately measure the retroreflection RA of road signs, safety clothing and other
materials.
The innovative optical system can measure up to 4 (four) simultaneous observation angles. The entrance angle (β) can be fixed ( −4° / +5° ) or it can be
continuously adjusted by the operator. The combination of adjustable entrance angle with the exclusive quadruple simultaneous observation angles allows precise determination of retroreflection according ISO 20471 and also to all international standards.
