Retro-Reflective Coefficient Tester

About Retro-Reflective Coefficient Tester

The Retro-Reflective Coefficient Tester is a precision instrument designed to evaluate the retro-reflective performance of high-visibility safety materials, including professional occupational warning garments and reflective school uniforms for children. By accurately measuring the retro-reflection coefficient, the system provides objective and reproducible data for quality assessment, ensuring compliance with national and international safety standards.

Application

The tester is suitable for a wide range of applications:

Traffic Safety Materials: Assessing reflective signs, markings, and school uniforms for visibility compliance.

Occupational Safety Garments: Evaluating high-visibility protective clothing used in construction, transportation, and industrial environments.

Vehicle Inspection: Measuring reflective markings on trucks and other vehicles.

Quality Control: Testing reflective materials, license plates, vests, and garments for standardized retro-reflection performance.

Test Procedures

Sample Preparation

Mount the reflective material or garment on the sample platform using the quick-change fixture.

Ensure the sample area corresponds to the testing aperture and standard requirements.

Calibration

Perform calibration using the included black and white plates to ensure measurement accuracy.

Measurement

Adjust the observation and incidence angles according to the testing standard.

Illuminate the sample with standard illuminant A and record the retro-reflective coefficient via the detector.

Repeat measurements for multiple points or samples as required.

Data Recording

Store test results on the TF card or view on the touchscreen interface.

Generate reports summarizing retro-reflection performance for quality assessment.

Maintenance Information

Regularly clean the detector and light source to maintain measurement accuracy

Inspect and tighten the sample fixture to prevent misalignment during tests

Calibrate the instrument periodically using the included plates

Ensure the touchscreen and data storage system function correctly

Store the instrument in a dry, dust-free environment to prevent sensor degradation
