In the realm of metal hardness testing, precision and reliability are non-negotiable. King Tester has set a new standard in the industry by introducing patented test blocks featuring laser-etched alphanumeric grids—a game-changing design that offers substantial advantages over traditional test blocks.

Enhanced Accuracy and Visibility

King Tester’s precision grid design improves test accuracy and visibility, ensuring consistent and reliable results. The laser-etched markings extend across the entire grid, with spacing that fully complies with ASTM E-10 Indentation Spacing standards. This meticulous design guarantees precise indentation placement while also making each indentation easily identifiable, significantly reducing the risk of errors during testing.

Simplified Record-Keeping

The alphanumeric grid system is a breakthrough for tracking and documentation. Each indentation is marked with a unique identifier, simplifying the logging process for daily verifications. This feature streamlines quality control workflows, making it easier to record and retrieve data while enhancing the overall efficiency of documentation.

Cost-Effectiveness: More Value Per Test

King Tester’s 4” x 4” test blocks deliver exceptional cost savings, with a reduction of over $1.00 per test. The larger block size accommodates more indentations, effectively reducing the cost per test and extending the block’s lifespan. This cost-efficiency makes King Tester’s blocks an economical choice for any metal testing laboratory.

Compliance and Traceability

Every King Tester test block is individually serialized and traceable, meeting ISO-17025 certification requirements. This guarantees that each block adheres to strict quality standards, ensuring confidence in the accuracy and reliability of test results. Additionally, the blocks fully comply with ASTM E-10 standards, reinforcing their industry-wide acceptance and regulatory adherence.

How King Tester Stands Out

While other manufacturers offer hardness test blocks that meet industry calibration standards, King Tester’s patented alphanumeric grid design provides distinct advantages:

Superior Accuracy – Ensures correct indentation placement with a laser-etched precision grid.
Effortless Record-Keeping – Alphanumeric markers make tracking and verification seamless.
Significant Cost Savings – Larger blocks reduce the cost per test.
Full Compliance & Traceability – Meets ISO-17025 and ASTM E-10 standards.

Conclusion: A Smarter Choice for Hardness Testing

King Tester’s patented test blocks with laser-etched alphanumeric grids are the superior solution for metal hardness testing. By offering enhanced precision, simplified record-keeping, cost-effectiveness, and industry compliance, these test blocks redefine what professionals can expect from their testing equipment.
