Key Features

• Instant Color-Change Results: Place one drop on any stainless steel surface. Within 60 seconds, observe the color reaction and compare it to the included chromatographic reference chart on the label to confirm the steel grade. The faster it turns red, the lower the material quality.

• Compact & Portable: The sealed 12ml bottle (approx. 6.7 × 2.2 cm / 2.64 × 0.87 in) fits easily in a toolbox, kitchen drawer, or lab coat pocket. Each bottle yields approximately 200 drops — hundreds of individual tests.
• Clear & Lasting Readings: Results are highly visible and remain stable, making them easy to photograph or document for commercial quality control or household inspections.
