Paper Schopper refractometer is a testing tool for testing the folding fatigue resistance of paper. It is an ideal testing tool for paper manufacturing enterprises, packaging manufacturing enterprises, textile manufacturing enterprises, wire rod manufacturing enterprises, etc. to detect product quality. Through this testing instrument, the folding endurance and folding endurance of the paper can be detected. At the same time, the instrument can be used for the detection of folding fatigue resistance of textiles, plastic films, wires and other products.
