Softness Tester Paper Softness Testing Instrument Best Hand-Feeling Softness Meter For Paper

Overview of the Paper Softness Testing Instrument

The RRD-01 Paper Softness Testing Instrument, also known as the Hand-Feeling Softness Meter, is a professional-grade device designed to measure the softness, flexibility, and hand-feel properties of various materials, including paper, tissue, non-woven fabrics, and tobacco sheets. This advanced instrument is widely used in industries such as packaging, food, pharmaceuticals, textiles, and laboratories to evaluate the physical qualities of end-products and semi-finished materials. Whether in R&D labs or quality control environments, the RRD-01 Paper Softness Testing Instrument delivers consistent, precise results, enabling users to maintain high standards across multiple industries.

Key Features of the Paper Softness Testing Instrument

1. High-Precision Softness Measurement
   The Paper Softness Testing Instrument accurately assesses the softness of materials by measuring the force required to push a sample through a precisely controlled slot. This force is registered as an indication of the sample's bending resistance, directly correlating to its softness level.

2. Automated and User-Friendly Operation
   Equipped with an automated electronic measurement system, the instrument allows for streamlined testing without subjective human interference. Simply place the sample on the slot platform, initiate the test, and allow the instrument to generate consistent, repeatable results.

3. Enhanced Testing Efficiency
   The automated return function improves efficiency by resetting the test setup immediately after each measurement. This feature is particularly valuable for labs with high testing volumes, reducing time between samples and boosting productivity.

4. Broad Application Across Industries
   Designed for applications beyond paper testing, the RRD-01 Paper Softness Testing Instrument is compatible with tissues, non-wovens, polyolefin films, sanitary tissue products, and certain textiles. Its wide applicability supports quality assessment across diverse fields.

5. Conformity with International Standards
   The RRD-01 complies with recognized industry standards, including:

   • GB/T 8942: Paper-Determination of Softness
   • ASTM D2923: Rigidity of Polyolefin Film and Sheeting
   • QB/T 1060: Softness Tester
   • TAPPI T498: Softness of Sanitary Tissues
   • ASTM D6828: Stiffness of Fabric by Blade/Slot Procedure
   • INDA IST 90.3, EDANA WSP 90.3: Standardized methods for non-woven softness testing.

Operating Principle of the Paper Softness Testing Instrument

The testing principle centers on a standardized bending resistance measurement. The sample material rests on a slot (separated by a fixed distance) between two plates. A blade (or probe) is then driven into the sample, penetrating it to an 8 mm depth. The maximum force exerted on the sample as it bends is recorded as its softness value. This blade/slot testing method allows precise differentiation of material softness by quantifying the force required for deformation.
