3nh YS4510 Portable Spectrophotometer – Measurement geometry: 45/0

The YS4500 series of portable spectrophotometers has been developed for high-precision colour and spectral measurements in industry, laboratories and quality management. The YS4580, YS4560 and YS4510 models combine modern 45/0 geometry, planar grating spectroscopy and high-performance CMOS sensors to deliver accurate and reproducible measurement results.

With various aperture sizes, UV support and modern colour management functions, the instruments are ideally suited for applications in the paint, plastics, printing, textile, coating and road signage industries. The combination of high measurement accuracy, ergonomic handheld design and powerful software makes the YS4500 series a professional solution for mobile and stationary colour control.

Areas of application

The YS4500 series is suitable for:

Paints, varnishes and coatings
Plastics and injection moulding industry
Printing and packaging
Textile and clothing industry
Ceramics industry
Road signs and reflective films
Automotive industry
Cosmetics and consumer goods
Laboratory and research applications
Colour matching and quality control

Models with a UV light source also enable precise measurements of fluorescent materials, optical brighteners and reflective surfaces. In particular, the YS4560 and YS4580 models have been specially optimised for the analysis of traffic signs, road markings and reflective films.

Apertures and flexible measurement

The various aperture sizes allow flexible adaptation to a wide variety of surfaces and sample sizes. This enables both large areas and small or structured measurement areas to be analysed precisely.

The small apertures are particularly suitable for:

narrow printed elements
textiles
small plastic parts
textured surfaces
edge areas
Laboratory samples with a limited measurement area

The YS4580’s large 20 mm aperture has been specially designed for:

traffic signs
Road markings
reflective films
uneven or coarse-grained materials
Large-area samples

Colorimetric functions

The instruments support comprehensive colour and quality analyses:

CIE LAB
XYZ
Yxy
LCh
CIE LUV
HunterLAB

Traffic sign and reflection analysis

The YS4560 and YS4580 models feature built-in functions for analysing road signs, road markings and reflective films. The instruments already include standard colour spaces in accordance with:

GB 2893
GB/T 18833

In addition, polygonal tolerance ranges can be defined individually. This allows for:

Luminance factor
Chromaticity coordinates
Reflectance values
PASS/FAIL assessments

for road signs and reflective materials to be checked quickly and in accordance with standards.

Software and data management

The YS4500 series supports professional colour management and quality control via PC software as well as Bluetooth and USB communication.

Functions:

Colour difference analysis
PASS/FAIL evaluation
Spectral diagrams
Colour matching support
Measurement reports
Quality reports
Colour comparison and archiving

Data storage:

YS4510:
500 standards + 20,000 measurement data points

YS4560 / YS4580:
1,000 standards + 30,000 measurement data

Special features

The instruments feature an ergonomic handheld design with a capacitive touchscreen and stable white reference calibration. Automatic calibration improves measurement reliability and reduces operator error.

The long-lasting full-spectrum LED light sources can perform more than 3 million measurements or last for approximately 5 years. The lithium-ion batteries allow for up to 5,000 measurements within 8 hours.

The YS4560 and YS4580 models also support Bluetooth communication for modern mobile colour management and wireless data transfer.
