Portable glossiness tester for ceramics and brightness stone measurement in three specification options: CS-300 single angle 60°, CS-300S single angle 60° with microporous 23mm, and CS-380 triangle 20°/60°/85° gloss meter.
Portable glossiness tester with three specification options for ceramic and stone surface brightness measurement

This portable glossiness tester addresses the practical need for objective surface shine measurement across various materials, particularly ceramics and brightness stones where visual appearance correlates with quality and specification compliance. The device enables quantifiable gloss assessment, which is essential for manufacturers, quality control professionals, and material specifiers who require consistent measurements rather than subjective visual evaluation. Three distinct specification models are offered—CS-300, CS-300S, and CS-380—each designed with particular measurement approaches to accommodate different industry standards and material types. The portable construction allows for both laboratory bench use and on-site measurements where materials cannot be easily transported.
Features and Construction

The glossiness tester range includes three primary models with different measurement capabilities, all designed for portable operation. Each variant focuses on specific testing requirements while maintaining the core function of surface gloss quantification.
Material and Build
The source text does not specify the exact housing materials or internal construction components of the gloss meters. However, as portable measurement instruments designed for professional use, they would typically incorporate durable casing materials suitable for both laboratory and field environments. The devices include optical measurement systems appropriate for gloss testing applications, with attention to consistent measurement performance across the available specification options.
Size and Practical Fit
While exact dimensions and weight are not provided in the source information, the description as 'portable' indicates a form factor designed for hand-held operation and easy transportation between testing locations. The CS-300S model specifically mentions a microporous aperture of 23mm, which defines the measurement area size for that particular variant. This portable design enables users to bring measurement capability directly to large ceramic pieces, stone slabs, or installed materials that cannot be moved to a fixed testing station.
Uses and Placement

The glossiness tester serves multiple applications where surface shine measurement provides valuable data for manufacturing, quality assurance, and material specification. Different industries and testing scenarios benefit from the various model configurations available.
Event or Professional Use
In professional manufacturing environments, the gloss meter supports quality control processes for ceramic tile production, stone finishing operations, and surface coating applications. The CS-380's triangle measurement capability at 20°, 60°, and 85° angles is particularly suited to industries requiring multi-angle gloss assessment according to specific standards. Trade shows, product demonstrations, and on-site client consultations can utilize the portable nature of the device to provide immediate measurement data.
Everyday Home Use
While primarily a professional instrument, the glossiness tester may also serve advanced DIY enthusiasts, material collectors, or restoration specialists working with ceramic artworks, decorative stones, or vintage surfaces where gloss matching is important. The portable design allows for assessment of installed materials in residential settings, such as kitchen splashbacks, bathroom tiles, or decorative stone features where original specifications may need verification during repair or extension projects.
Benefits and Buying Value

The glossiness tester provides measurable advantages over subjective visual assessment, with different model options offering specific benefits based on testing requirements.
Reuse and Low Maintenance
As a measurement instrument rather than a consumable product, the gloss meter offers repeated use over time with minimal ongoing requirements beyond basic care. The portable design reduces the need for duplicate instruments in multiple locations, as a single device can service both laboratory and field testing needs. Without moving parts subject to wear in the measurement system, the device maintains calibration and performance with proper handling and storage.
Why Choose This Product
The availability of three distinct specification models allows users to select the most appropriate instrument for their specific testing protocols—whether requiring standard 60° measurement, the CS-300S's microporous aperture for specialized applications, or the CS-380's comprehensive triangle measurement capability. This product provides objective gloss data that supports quality documentation, specification compliance verification, and consistent production standards across batches or time periods.
