Product Introduction 
The grammage sampler operates on the mechanical punching principle. The paper or board to be tested is placed under the sampler's blade. By applying manual or pneumatic pressure, the precision circular blade punches out a standard specimen of specified area in a single stroke. The device is designed according to QB/T 1671, cutting specimens with an area of 100 cm², which is the standard area basis for paper grammage calculation. The punched specimen can be weighed directly on an electronic balance; dividing the weight by the area yields the paper's grammage. The integrally cast frame ensures precise long-term alignment between the blade and base. Combined with the specialized wavy blade and pressing cap, the cutting process is efficient and effortless, producing specimens with clean, burr-free edges.

Key Features 
Standard Area Precision Cutting Cuts specimens with an area of 100 cm², strictly following QB/T 1671, providing a standard specimen basis for paper grammage determination.
Integrally Cast Stable Structure Cast iron integral frame ensures dimensional stability and structural rigidity over long-term use.
Wavy Blade, Effortless and Durable Blade made of special No.10 steel with high-temperature quenching; the wavy edge design effectively reduces cutting pressure and extends service life.
Innovative Pressing Cap Process Equipped with a pressing cap that flattens the specimen before cutting, reducing sampling errors caused by paper curl or wrinkling.
Wide Thickness Adaptability Supports single or multiple layers of paper (0.1-3.0 mm) and single-layer board (<0.6 mm), meeting the sampling needs of various materials.
High Precision Punching Cutting accuracy of ±0.35 mm ensures accurate specimen area, providing a reliable data foundation for grammage calculation.
Simple and Efficient Operation Manual operation with a simple and intuitive structure requires no power supply; sampling is fast, suitable for frequent use in laboratories and on production floors.
Replaceable Blade Design The blade is replaceable. When the original blade becomes worn after extended use, original replacement blades are available from our company.

Main Technical Specifications 

FAQ 
1. Why is the cut specimen area 100 cm²?
100 cm² is the standard specimen area for paper grammage (basis weight) determination, specified in the QB/T 1671 standard. This area simplifies grammage calculation: weigh the specimen in grams and multiply by 100 to obtain the grammage in g/m².

2. What if the blade becomes worn or dull?
The blade is replaceable. If cutting becomes difficult or specimen edges show burrs, the blade may be dull. Contact us to purchase an original replacement blade; cutting precision and quality will be restored after replacement.

3. What thickness of board can the device cut?
It supports single or multiple layers of paper from 0.1 to 3.0 mm and single-layer board less than 0.6 mm. Materials exceeding this thickness may cause cutting difficulty or irregular specimen edges and are not recommended.

4. What is the function of the pressing cap?
The pressing cap applies pre-pressure to the specimen before cutting, flattening the paper against the base surface. This effectively avoids cutting dimension deviations caused by paper curl or wrinkling, improving sampling accuracy.

5. Does the device require regular maintenance and lubrication?
The integrally cast structure requires minimal maintenance. Keep the equipment clean and periodically apply a small amount of lubricating oil to the moving joints. The blade is a consumable part and should be replaced as needed based on usage frequency.

6. Can it be used for sampling non-paper materials?
The device is primarily designed for grammage sampling of paper, board, and similar flexible sheet materials. For other materials such as plastic films or textiles, it may be used cautiously if the thickness falls within the applicable range and the material does not damage the blade. A small-scale trial is recommended first.
