Introduction
R004 is a 45/0 large‑aperture spectrophotometer with 45° annular illumination and 0° detection, compliant with CIE No.15 and international standards. Adopting concave grating and dual‑array CMOS sensor, it features a Φ20mm large measuring aperture and independent UV light for fluorescent samples. It supports high‑precision reflectance and color difference measurement, built‑in traffic sign standards, custom tolerance, and professional PC software, widely used for color quality control in food, textile, plastic, ink, ceramic, and traffic facilities.
Advantage
Professional 45/0 Optical Structure & High Visual Consistency Adopts 45° annular illumination and 0° receiving structure, close to human vision. It reduces interference from texture, tilt and position, ensuring high accuracy and repeatability on textured, granular or uneven surfaces, making measurement more stable and reliable. |
Φ20mm Large Aperture for Uneven & Food Samples Equipped with a large Φ20mm measuring aperture, it is ideal for granular, striped or uneven samples such as food, agricultural products, fabric and stone. One measurement represents overall color, avoiding repeated averaging and improving testing efficiency. |
Built‑in Traffic Sign Standards & One‑Key Measurement Preloaded with GB 2893 and GB/T 18838 standard colors, it supports polygonal and rectangular tolerance settings. It can directly measure luminance factor and chromaticity coordinates of traffic signs, markings and reflective films with one key, highly efficient. |
Smart Touch Screen & High‑Speed Measurement & Transmission 3.5‑inch TFT capacitive touch screen with Android system offers smooth operation. Measuring time is only about 1 second. USB and Bluetooth 4.0 enable fast data transfer. It supports single and average measurement, greatly improving work efficiency. |

Application
1.Traffic Sign & Reflective Material Industry
As a professional traffic sign colorimeter, it measures luminance factor and chromaticity coordinates of roadsigns, markings and reflective films. Built-in national standards and custom tolerance help achieve fast andstandardized quality inspection.
2.Plastic & Electronic Manufacturing
This large aperture color tester controls color difference of plastic shells, electronic parts andsurface-textured components. Stable measurement reduces texture interference, ensuring batchconsistency and appearance quality of plastic and electronic products.
3.Coating, Ink & Textile Industry
Suitable for coatings, inks, textiles and dyed materials, it supports fluorescence measurement with UV light.It monitors color difference in production, ensures batch consistency, and provides reliable data forprinting, dyeing and coating processes.
4.Ceramic, Stone & Wood Industry
Ideal for ceramic tiles, stone, wood and textured surfaces the large aperture reduces the influence of grainand unevenness. It provides stable and accurate color data for quality control in ceramics, furniture andbuilding materials.
