Overview
ZTT-101A multi-angle inverse reflection mark measurement instrument is a special instrument used for the measurement of inverse reflection coefficient (R ′) of traffic sign materials under the Tiandi Spark brand. The instrument is suitable for quality control and testing of inverse reflection mark materials by material production units, mass supervision departments, engineering construction and supervision units.
Features
1. The observation angle is continuously adjustable in the range of 0.2 °~ 2.0 °, and the reading accuracy is 0.002 °
2. The incident angle is continuously adjustable in the range of -40 °~ + 40 °, and the reading index is 1 °
3. Standard A Illuminant (Color temperature 2856K) and silicon diode detector
4. Measurement range 0~ 9999cd · lx-1 · m-2, resolution 0.1 cd · lx-1 · m-2
5. Lithium battery power supply, Continuous Operating Time of more than 30 hours, support indoor and outdoor measurement
6. Data storage capacity up to 10,000 test messages
7. Equipped with 4.5 inch 854x480 Touchscreen
8. Support TF memory card to connect to the computer
Principle
The instrument irradiates the sample through adjustable observation angle and incident angle, using standard A Illuminant and filter-corrected silicon diode detector to measure the inverse reflection coefficient of the sample, and the detector meets the CIE standard Photometric Observer Light spectrum Optical Efficiency V (lambda) requirements.
Applications
Material production unit, mass supervision department, engineering construction unit, supervision unit
