SLW with built-in sensor Textiles, natural fabrics, synthetic fabrics, yarns 0 . 3-30% humidity-10 to +60 °C
Measuring device with built-in sensor for determining the water content of textiles / easy to use / small, handy, precise, can be used anywhere / fast and cost-effective textile moisture measurement / long-term stable / lifetime support
The SLW moisture meter is suitable for quick and easy determination of the water content or residual moisture of textiles, fabrics, yarns, wool and other products such as yarn spools, fabric rolls, natural fabrics, synthetic fibers, cotton, viscose, polyamide and many more. It can be used in the manufacturing process as well as for finished products.
The water content of fabrics and yarns significantly influences their tensile strength and elasticity. With the SLW moisture meter you can determine the water content within a few seconds and thus control and guarantee the quality of your products.
The device is also often used to check garments and textiles before packaging, for example in laundries, to prevent mold or odor development due to excessive moisture.
As soon as the measuring tips touch the textile, the measuring instrument immediately displays the water content. Due to the characteristic curves stored in the device, the current water content of the selected material is shown directly on the display without the need for conversion via tables.
