TZ-901 Retroreflectometer
·
Overview
The TZ-901 Retroreflectometer is a new product independently developed and produced by Zibo Taizhan Electronic Products Co., Ltd. in accordance with GB21861-2014 "Items and Methods for Safety Inspection of Motor Vehicles". It features fully intelligent design, LCD display, long-life light source, and a detachable probe.
The TZ-901 Retroreflectometer is an instrument used for on-site measurement of the photometric performance (retroreflection coefficient R＇) of retroreflective materials. It is a convenient handheld photoelectric instrument that can be used to measure the reflective performance of reflective markings on truck-type motor vehicle bodies, as well as to detect the retroreflection coefficient of vehicle rear marker plates.
The instrument consists of an optical system, detection amplification system, power supply and its control system, display system, and instrument calibration block.
It offers high accuracy, small error, good repeatability, compact size, and simple operation.
