RetroSign GRX has a pre-set measurement programme
199 Delta’s new RetroSign GRX retroreflectometer is a portable instrument for measuring retroreflection of road traffic signs as well as high-vis clothing and number plates.

Delta says that its RetroSign GRX offers many features and supports a preset measurement programme, making it easy to measure and evaluate results on the spot.

In addition, the RetroSign GRX software and App/tablet solution feature asset management capabilities for data processing and storage, including data search capability.

The GRX has a built-in function for setting minimum retroreflection levels. A minimum level can be set for both the sign background colour, the sign legend colour and/or colour contrast between the two. It allows the user to instantly know if a sign passes or fails minimum requirements.

From a practical point of view, the setting for minimum reflection allows maintenance crews to immediately change road traffic signs which do not meet the requirements. This avoids a time-consuming and therefore costly second visit to the site to make essential changes to the sign.

For the US market, Delta has expanded the pass-fail function to facilitate the sign library MUTCD - Manual on Uniform Traffic Control Devices. This optional feature hosts the complete MUTCD library in the instrument and tablet, comparing measurement results against the minimum requirements stated in the library. Again, this feature will inform the user instantly of the sign’s conditions.

In addition, RetroSign GRX can take a picture of the measured sign and compare it to the references in the MUTCD library in order to confirm whether the sign meets the requirement or not.

The tablet option supports marking the defect in the photo image and linking it to a note, if there are conditions related to the performance of the sign requiring this.
