It is used for measuring retroreflection of road traffic signs, high visibility clothing, license plates and conspicuity tapes.
RRGX is built in accordance with existing standards to allow for retroreflection measurement of various colours and all type of retroreflective materials including fluorescence types.
RetroSign RRGX uses a LED light source and meets the sensor response as stated in ASTM E 1709 for combining the CIE eye response and CIE illuminant 'A'.
It has a rugged design and is built for long-lasting field work even if it can also be used in the laboratory.
The software is simple and intuitive and guides the user through the different steps of a measurement program.
It GRX allows the user to create templates with almost unlimited measurement related information (pre-defined or specific entries) of series of measurements with the same basic data. An ID for the user can be entered.
It complies with the following standards: EN 12899 (road traffic signs), EN 20471 (high visibility clothing), ASTM E 1709 & ASTM E 2540 (road traffic signs) and ASTM E 1809 (high visibility clothing).
RRGX is based on point aperture geometry comparable to laboratory readings reflecting real-world driving conditions and allows detection of incorrect application of direction sensitive microprismatic sheeting.
It uses advanced sensor technology to allow for measurement of up to seven observation angles in addition to automatic colour recognition.
The angles available to the user are:
0.2o; 0.33o, 0.5o; 0.7o, 1.0o, 1.5o and 2.0o.
A built-in digital camera makes it possible to take pictures of signs as well as scan barcodes and QR codes for asset management purpose.
The man-machine user interface is through a large 5” WVGA colour touch display clearly visible even in bright sunshine.
The instrument automatically detects and compensates for ambient light present which could affect the measurement result.
The working range of the instrument is 0 – 2.000 cd x lx-¹ x m-².
RRGX scalability - also after purchase - is an extremely powerful feature. Users can upgrade their system in the field as their needs
change.
It is offered in three base models where the figure tells the number of observation angles offered
·· RRGX-1 (1 entrance and 1 main observation angle)
·· RRGX-3 (1 entrance and 3 observation angles)
·· RRGX-7 (1 entrance and 7 observation angles)
The entrance angle is provided as a front adapter with one of the two standard angles of -4o (ASTM) or +5o (CEN) supplied with the instrument.
Further entrance angles of +10o, +15o, +20o, +30o, +40o and +45o are offered for special measurement purposes.
