Product History: First launched in 2018, this internal calibration standard has been refined across 12 production batches to ensure metrological reliability and compatibility with global testing protocols.

Design Concept: Engineered for precision consistency, the design prioritizes traceable accuracy, minimal thermal drift, and seamless integration into automated lab workflows.

Selling Points:

·ISO/IEC 17025-compliant reference values

·Batch-specific calibration certificates included

·Optimized geometry for repeatable instrument alignment

·Anti-static surface treatment prevents particulate adhesion

·Compatible with spectrophotometers, CMMs, and optical comparators

Materials: Aerospace-grade 304 stainless steel body; laser-etched markings with ceramic-based ink; PTFE-coated contact surfaces for low friction and corrosion resistance.

Packaging Dimensions: 12.5 cm × 8.3 cm × 4.0 cm (L×W×H); lightweight rigid foam insert inside recyclable kraft cardboard box; total shipping weight: 280 g.

Note: Due to batch-specific manufacturing variances, item numbers may differ slightly between lots. Units are shipped randomly unless otherwise specified.
