• Standards Compliance: Adhering to GB/T 1540, ISO 535, QB/T 1668, TAPPI T441, and QB/T 1671, this system ensures your tests are globally recognized, alleviating concerns over regulatory non-compliance in procurement decisions.
• Cost-Effective Quality Control: By accurately measuring water absorption (in g/m²), it helps identify sizing issues early, preventing production defects and reducing rework costs in lab and industrial settings.

Whether you're a researcher analyzing paper properties or a purchaser sourcing dependable lab tools, this combo minimizes downtime and maximizes insights, transforming potential testing bottlenecks into seamless workflows.

How It Solves Customer Pain Points

Laboratory professionals often struggle with equipment that lacks integration, leading to mismatched samples and inaccurate absorption readings. The PN-COBB Tester with Sample Cutter resolves this by offering a dedicated sampler that cuts precise φ125 mm samples with a thickness range of 0.1 to 1.0 mm, perfectly suited for the tester's 100 cm² test area. No more dealing with irregular cuts or excess water variability— the 10 kg roll and timed protocols (e.g., Cobb30 with 20±1s excess water removal) ensure consistent, repeatable results. In humid or variable environments (up to 85% humidity at 20±10°C), its durable design maintains performance, tackling the challenge of environmental impacts on testing reliability.

Technical Specifications: Engineered for Precision

The PN-COBB Tester features a test area of 100 cm² with an exceptional precision of ±0.2 cm², paired with a test water volume of 100 mL ±5 mL for controlled exposure. Its robust roll measures 200 mm in length (±0.5 mm) and weighs 10 kg (±0.5 kg), delivering uniform pressure during absorption phases. Compact dimensions of 396 × 315 × 300 mm and a net weight of approximately 32 kg make it easy to integrate into any lab setup.

Complementing this, the PN-CAC125 Sample Cutter boasts a sampling size of φ125 mm with an error margin of just ±0.2 mm, handling thicknesses from 0.1 to 1.0 mm effortlessly. Operating in standard room conditions (20±10°C, <85% humidity), it has dimensions of 310 × 250 × 400 mm and a net weight of about 26.5 kg, emphasizing its sturdy yet manageable build for daily use.

Emphasizing precision at every step, this equipment supports detailed protocols like Cobb60 (45±1s excess removal) and Cobb1800 (1755–1815s), allowing for in-depth analysis without compromising accuracy. It's not suitable for unsized or embossed papers under 50 g/m², ensuring focused application where it excels.
