You can rely on it for quality control, production monitoring, and process optimization, ensuring accurate and repeatable measurements essential for your product evaluation and research needs.
Applications
Paper Roughness and Air Permeability Tester (TMI) simultaneously measures the surface roughness and air permeability of paper and paperboard, serving as an indispensable laboratory instrument for quality inspection and process control.
Standards
Surface Roughness:
ISO 8791-2 Paper and paperboard - Determination of roughness/smoothness (airflow method) - Part 2: Bendtsen method
SCAN P21 Industrial standard method for measuring paper surface roughness
NEN 2012 Determination of roughness of paper and paperboard - Bendtsen method
BS 4420 Paper and paperboard - Determination of Bendtsen roughness
DIN 53108 Paper and paperboard tests - Determination of roughness by the Bendtsen method
Air permeability:
ISO 5636-3 Paper and paperboard. Determination of air permeability (medium range). Part 3: Bendtsen Method

DIN 53120-1 Tests for Paper and Paperboard: Determination of Air Permeability: Part 1: Determination of Average Air Permeability by the Bendtsen Method
Features
1. Constant pressure control with dual measurement: Samples are clamped by the indenter and subjected to constant pressure to perform both roughness and air permeability measurements.
2. The indenter incorporates an integrated air pressure sensor that continuously monitors and records pressure fluctuations, ensuring accurate and consistent measurement data.
3. The device features a feedback mechanism enabling operators to make real-time adjustments.
4. User-friendly touchscreen system: Equipped with a 7-inch color touchscreen featuring intuitive icon-based navigation. No language switching required during operation, enabling quick mastery even for novices.
5. Flexible and efficient probe design: The roughness probe covers 10cm² and connects to the main unit via a flexible hose, facilitating rapid multiple measurements across different areas.
6. An optional smoothness probe is available to meet specific smoothness requirements under designated standards.
7. Cost-saving design for easier maintenance: The measurement ring is designed for quick replacement without needing to swap the entire probe assembly, significantly reducing long-term maintenance costs.
