Operation and maintenance of circular quantitative sampler products: 1. It adopts special No. 10 steel knife edge and is durable! 2. The punching is smooth and the sample has no burrs! 3. The whole machine adopts one-piece casting structure, which is more solid and not easy to deform! 1. Place the instrument in a position on a stable and stable work surface. 2. Place the paper flat on the center of the chassis and press the beam with your left hand to prevent the sampler from lifting forward when the lever is pressed. Slowly press the lever to complete a sampling. The sample taken falls into the chute and slides out from the side by the chute. 3. Slowly release the lever and the upper punch returns to the starting position. Take out the sample and perform the corresponding test.
