RetroSign GR1 Safety

The professional choice for measuring retroreflectivity of safety clothing.

Maintaining optimum performance in retroreflectivity of safety clothing after e.g. washing or rinse is essential in protecting workers operating in e.g. busy road zones. GR1 Safety is the answer to the needs of insuring that retroreflectivity of worker’s clothes can still be used safely to protect workers on the road at night. It measures in according with EN 471 and EN 20471 (entrance angle: +5° and observation angle: 0.2°).

GR1 Safety is based upon an accurate point measurement geometry offering superior performance in measuring retroreflective sheeting material due to its accurate, sensitive and durable filters

The instrument operates with a reproducibility of +/-5% and a repeatability of +/-2%. The internal memory stores more than 250,000 readings.
