BYK micro-gloss 60° 4561 Gloss Meter

Overview of BYK 4561 Micro-Gloss 60° Gloss Meter

The BYK micro-gloss 60° 4561 is a single-angle handheld gloss meter—featuring the most universal and widely implemented measurement geometry in the industry. The instrument is manufactured by BYK-Gardner (Germany), the global leader in surface quality control solutions.
With an extended measurement range and standard aperture size, the BYK 4561 delivers precise gloss evaluation across all material types, ranging from paint coatings and polymer thin films to mirror-polished metal surfaces, without requiring frequent re-calibration.

BYK micro-gloss 60° 4561 Gloss Meter

– The BYK 4561 micro-gloss 60° gloss meter has stood as the definitive industry standard for gloss measurement for many years. It is the only gloss meter that combines premium accuracy, seamless ease of use, and multi-functional capabilities—critical for modern testing requirements.

– The BYK 4561 micro-gloss 60° gloss meter features an ergonomic industrial design and effortless handling. Operation via the navigation scroll wheel paired with a sharp color display and easy-to-navigate menu makes gloss testing easier than ever before.

BYK 4561 Gloss Meter: German Standards for Semi-Gloss Surfaces
In the paint manufacturing, plastics, automotive, and metal processing industries, surface gloss control is a mandatory Quality Control (QC/QA) criterion. To achieve objective results, flawless repeatability, and strict compliance with international specifications, German-engineered instrumentation remains the top choice for global enterprises.
The BYK 4561 gloss meter (fully designated as the BYK-Gardner micro-gloss 60°) represents the symbol of accuracy and durability in the global metrology sector, specifically engineered for medium-gloss (semi-gloss) surfaces.

Outstanding Features of the BYK 4561

Absolute Accuracy and Long-Term Stability
BYK’s advanced optical system ensures that measurement repeatability and inter-instrument agreement (IIA) operate with exceptionally low error margins. This streamlines measurement data synchronization across your entire supply chain, from R&D laboratories to the production line.
LED Light Source Technology with a 10-Year Warranty
Unlike conventional gloss meters utilizing halogen lamps that easily suffer from luminance degradation over time, the BYK 4561 integrates a cutting-edge LED light source. BYK-Gardner provides a 10-year warranty on the lamp supply, drastically minimizing routine maintenance and component replacement costs for enterprises.
Versatile Testing Modes & Intelligent Evaluation Features
Statistic Mode: Beyond displaying the average value, the instrument automatically computes the standard deviation, variance range, and Max/Min limits to evaluate surface gloss uniformity.
Difference Mode: Enables the configuration of a target reference standard along with specific tolerance thresholds. Measurement readouts render intuitive, color-coded Pass/Fail judgments directly on the display screen.
Continuous Scan Mode: Supports rapid evaluation of gloss uniformity over large surface areas.
Modern Interface with Ergonomic Operation
The device features a high-resolution, sharp color display paired with a smart scroll wheel, enabling technicians to configure and operate the unit effortlessly with a single hand.
Integrated with an intelligent Auto Diagnosis system, the meter automatically monitors the calibration tile’s condition and prompts the operator for calibration when necessary.
