Overview

The fabric moisture permeability tester can use moisture absorption or evaporation methods to measure the moisture permeability of fabrics, and is suitable for various fabrics with a thickness of less than 10mm. Perspective rate refers to the mass of water vapor passing vertically through a unit area of a specimen under specified temperature and humidity conditions on both sides of the specimen for a specified period of time,

Product Details

1、 Main purpose

LFY-216BfabricMoisture permeability testerIt uses the moisture absorption cup method to determine the ability of water vapor to pass through fabrics. This instrument is used to measure the moisture (vapor) permeability of various fabrics (including moisture permeable coated fabrics) as well as non-woven fabrics such as cotton and space cotton used in clothing. Moisture permeability can reflect the sweat and moisture wicking performance of clothing, and is one of the important indicators for evaluating the comfort and hygiene of clothing.

　　IIInstrument features

Maintenance method

1. Regular cleaning: Sensors, buffer chambers, and other parts should be cleaned regularly. First, use a vacuum cleaner or cleaning cloth to remove dust, ash, and other debris, and then use specialized cleaning agents or alcohol to wipe them clean.

2. Attention to storage: The storage environment should be kept dry, clean, well ventilated, at a suitable temperature, and avoid direct sunlight and high temperatures.

3. Prevent damage: Avoid collisions, drops, and water immersion during use, and protect the sensors and other components of the instrument.

4. Regular calibration: Regular calibration is required to ensure accurate measurement results.

5. Maintenance and repair: In case of malfunction or need for repair, professional maintenance personnel should be sought for timely repair, and unauthorized disassembly or repair is not allowed. At the same time, avoid excessive or overloaded operation during use to extend the service life.
