STT-101 type inverse reflection sign measuring instrument

First, product overview

STT-101 type inverse reflection sign measuring instrument is a kind of instrument used for measuring the photometric properties (inverse reflection coefficient R ') of inverse reflection material. It is a portable photoelectric instrument is convenient, can be measured for Retroreflective Signs for traffic safety management and highway, railway, aviation and other relevant departments, can also be used for the measurement of goods vehicle body reflective logo of reflective properties, used for monitoring the quality of production of retroreflecting reflective materials, Retroreflective Signs materials meet the relevant standard requirements to ensure that.

The instrument is composed of an optical system, a detecting and amplifying system, a power supply and a control system, a display system and a calibration block of the instrument.

The design of the instrument according to the relevant GB/T 26377-2010 Retroreflectometer "GB/T 188833-2012" and the "road traffic" reflective film standards, conforms to the GB21861-2014 standard of "motor vehicle safety and technical inspection items and methods". Showing the value for the instrument calibration, calibration block is also equipped with a set of calibration instrument indication, to ensure accurate and reliable measurement instrument; instrument LCD digital display meter display measurement value; and the 2 section 5, Ni MH battery as a power source.
