Overview
The RFM-200A reverberation reflection field measurement instrument is a professional test equipment launched by the EVERFINE brand. It is specially designed for on-site measurement of road traffic standards, the reflection intensity coefficient or reflection coefficient of the reverberation reflection device and other photometric performance. The system fully meets the requirements of ASTM, CIE, DIN and other international standards. It integrates standard illuminant and reverberation reflection photometric measurement functions, and has the characteristics of stable and reliable testing, small size and light weight.
Principle
The instrument works based on the measurement principle of reverberation photometry. The built-in standard illuminant irradiates the measured reverberation reflection sample at a specific incident angle (-4 °). High Accuracy Silicon Photocell, photovoltaic cell detector receives the light signal reflected back by the sample at a specific observation angle (0.2 °). The reflection intensity coefficient or reflection coefficient of the sample is calculated by measuring the ratio of the reflected light intensity to the incident ray illuminance.
Applications
Road traffic standards, reflector photometric performance test
Steps
1. Choose the appropriate power supply method (battery, AC adapter or car cigarette lighter adapter) according to the power supply environment.
2. Use the configured reference template to calibrate the system.
3. Place the test reflection sample in the test area (diameter 25mm).
4. Start the test through the instrument panel or wireless WIFI remote operation.
5. The instrument automatically completes the measurement and automatically switches between multiple ranges to ensure accuracy.
6. Test data can be stored inside the instrument (more than 1000 sets), or exported through the USB interface.
Notice
• Before use, make sure to calibrate the system using the reference template to ensure measurement accuracy.
• Note that the geometric conditions of the instrument such as incident angle, observation angle, Illuminant and detector aperture opening angle must meet the requirements of relevant standards.
• Please select the appropriate power supply method according to the site conditions and ensure that the Power Adapter specifications are correct.
• The instrument has a multi-range automatic switching function. Please ensure that the luminosity value of the measured sample is within the instrument range (0.1-2000 cd/lx/m ²) during measurement.
Regular maintenance of the detector (High Accuracy Silicon Photocells, photovoltaic cells) to ensure its long-term stability.
• When operating remotely via wireless WIFI, please pay attention to network connection stability.
