Shore OO Durometer, Handheld Hardness Tester for Soft Silicone Foam Latex | Designed for ultra-soft sponge & foaming materials. Portable analog dial, metal housing.

Shore OO Durometer Hardness Tester This analog Shore OO hardness tester is manufactured per ASTM D2240 standard, specially developed to test the hardness of ultra-soft elastic materials that cannot be measured by Shore A hardness meter. Key Specifications Scale: Shore OO (HOO) Measuring Range: 0 ~ 100 HOO Graduation Value: 1 HOO Accuracy: ±1 HOO Indenter Force: 0.203 N ~ 1.111 N Standard: ASTM D2240

• Complies with ASTM D2240 Standard: Professional Shore OO hardness gauge follows ASTM D2240 specification, measuring range 0-100 HOO, accuracy ±1HOO, resolution:1HOO. Reliable test data for industrial & laboratory use.
• Designed for Extra Soft Materials: Ideal for soft silicone, latex, foam rubber, sponge, foaming rollers, soft elastomers and similar cushion materials. Note: Sample thickness ≥3mm for accurate readings.
• Precision Force Indenter Structure: Indenter end force: 0.203N ~ 1.111N (20.71gf ~ 113.37gf). Optimized pressure head prevents over-compression of low-density foams, guaranteeing stable measurement.
• Durable Portable Analog Dial Design: Metal housing with clear dial scale, intuitive pointer reading. Compact handheld structure, lightweight, easy to carry for on-site inspection and lab hardness testing.
• Wide Application Scenarios: Widely used in silicone products, foam padding, foaming rubber rollers, soft elastic materials, cushion materials quality inspection, factory QC and material research laboratory.
