The DL-812S is a robust and reliable hydrostatic pressure testing instrument, specifically engineered for labs that require high precision and pneumatic clamping stability. With a focus on accuracy and ease of use, this model is ideal for assessing the water penetration resistance of textiles, non-wovens, and coated fabrics.

Unlike the fully automated series, the DL-812S offers a 3000ml integrated water tank for manual supply, providing a cost-effective yet high-performance solution for standard laboratory environments.
