Application field: Transportation
The GT-RM001 Road Retroreflection Marking Measuring Instrument Road Retroreflective Marking Measuring Instrument (Retroreflective Measurement Standard Device) is a specialized optical measurement device used to measure the reflective performance of road markings. It is suitable for on-site testing of the retroreflective coefficient of road markings by relevant departments such as completion acceptance, construction, and testing. It meets current standards and has the function of real-time temperature and humidity detection and GPS positioning storage of detection data.

Details Introduction
The GT-RM001 Road Retroreflection Marking Measuring Instrument Road Retroreflective Markings Measuring Instrument/Retroreflective Measurement Standard Device is a specialized optical measurement device developed and produced by Beijing Zhongjiao Engineering Instrument Research Institute, used to measure the reflective performance of road markings. The measured parameter is the retroreflective brightness coefficient RL ‘(also known as specific brightness) of the markings, with a unit of mcd · m-2 · lx-1. This instrument is easy to operate, reliable in measurement, and can be used for both laboratory and on-site measurements. It is an instrument used by production, quality supervision, engineering construction, supervision, and teaching and research units to measure the optical properties of highway markings.
This instrument is designed based on standards and is designed in accordance with relevant international technical documents and current national standards in China, such as Publication No. 72 of the International Commission on Illumination (CIE), ASTMD4061-94 in the United States, DIN67520 and 67521 in Germany, GB/T26377-2010 Retroreflective Measuring Instruments in China, GB/T16311-2009 Quality Requirements and Testing Methods for Road Traffic Markings, JJG (Transportation) 059-2004 Metrological Verification Regulations for Retroreflective Measuring Instruments, JJF1809-2020 Calibration Specifications for Retroreflective Measuring Instruments, etc.

   Instrument maintenance and precautions
5. The instrument is equipped with optical components, and attention should be paid to moisture prevention, especially when used for field measurements in winter. The temperature should not change suddenly. If the outdoor temperature is below -10 ℃, the instrument should gradually move to an indoor temperature above+20 ℃, otherwise the surface of the optical components of the instrument will be affected by frost and affect its use.
   During use and handling, attention should be paid to shock resistance and handling with care. The fasteners of the instrument must not be loosened or disassembled at will to prevent damage to components or inaccurate measurement values.
   The accuracy of the measured values is closely related to the zero adjustment plate and calibration plate, so the calibration plate equipped with the instrument should be properly stored and not dirty or damaged. If there is contamination or damage, the supplier should be contacted for replacement.
   When the instrument is not in use, please place it inside the instrument box and pay attention to dust prevention.
   When the instrument is left unused for a long time, it should be charged every 2-3 months, otherwise the battery will be damaged.
