A:YM-13 – Non-Adjustable Height Model B:YM-13 – Adjustable Height Model brief introduction The YM-13 water stain tester installs the sample on the sample holder and forms a 45 ° angle with the horizontal, the center of the sample is located at a specified distance below the nozzle, and the sample is sprayed with a specified volume of distilled water or deionized water. By comparing the appearance of the sample with the evaluation standards and pictures, the water level is determined, which is suitable for measuring the moisture resistance of various water-resistant and water-repellent finished fabrics. This instrument is not suitable for measuring the water permeability of fabrics, so it cannot be used to predict the rain permeability of fabrics. All stainless steel body, corrosion resistance is more durable, the whole machine is made of stainless steel, the parts in contact with water have no rust, pollution risk, smooth surface is easy to clean and no residue
