Ceramic Gauge Block 1/5Pcs ISO Grade 0, Factory Inspection Report, Calibration for Various Measuring Instruments, Customizable

Product Overview

This single zirconia ceramic gauge block is a high-precision rectangular length standard tool, ideal for calibrating calipers, micrometers, height gauges and other precision measuring instruments. Made of premium zirconia ceramic, it offers superior hardness, wear resistance and dimensional stability compared to steel gauge blocks. ISO Grade 0 , it meets strict metrology standards and is widely used in precision machining, mold making, quality control and laboratory calibration, serving as a reliable reference standard for dimensional verification.

Product Features & Specifications

· Material: High-quality zirconia ceramic, with hardness far exceeding steel gauge blocks, long service life
· Accuracy Grade: Grade 0 meets international metrology standards
· Precision: Measuring surface mirror-lapped, with excellent flatness and parallelism
· Dimensions:
- Length ≤ 10mm: 30 × 9mm (W × H)
- Length > 10mm: 35 × 10mm (W × H)
📌Note: Only the measuring length (L) is precision-ground; width (W) and height (H) are non-precision dimensions
· Chamfered edges: Rounded edges for ≤10mm blocks, blunted corners for >10mm blocks to reduce scratches and improve handling safety
· Clear laser marking: Size and batch number engraved for easy identification and traceability
· Packaging: Each block individually packed in a plastic case for protection and storage
· Application: Calibrating calipers, micrometers, height gauges, and as reference standard for dimensional inspection
