The Puncture Tester is a standard instrument specifically designed for measuring the puncture resistance of corrugated board. It is widely used in quality inspection at board and box manufacturing plants, material research at scientific institutions, and performance evaluation at commodity inspection agencies. The instrument is designed and manufactured in accordance with ISO 3036 (Determination of puncture resistance of board) and GB/T 2679.7 (Determination of puncture resistance of paperboard). It features a measuring range of 0-48 J, equipped with four scales—A (0-6 J), B (0-12 J), C (0-24 J), and D (0-48 J)—with the smallest graduation of 0.05 J, meeting testing needs from thin board to heavy-duty corrugated board. The instrument includes a quick-clamping mechanism, an operating handle with automatic return function, and comprehensive safety protection features for safe and reliable operation. With overall dimensions of 900×800×410 mm and a weight of approximately 100 kg, it is a robust, durable, and indispensable testing device for puncture resistance evaluation and quality control in the board and box industry.
