Water vapor permeability is a measure of the passage of water vapor through a material. It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR) - which is basically the mass of water vapor that is transmitted through a measured area in a specific unit of time under specified conditions of temperature and humidity.ASTM D 1653 is a standard test method used to determine the permeability of organic coatings to water vapor and gases. The test involves immersing coated test panels in water or other liquids, and measuring the rate of water vapor or gas transmission through the coating. The water vapor permeability tester places the positive cup in the test apparatus. After equilibrating, weigh the object to obtain its initial weight. Then, testers test and weigh it again. The formula uses the mass difference from the second weighing. It uses the difference to find the sample’s moisture permeability.Water Vapor Permeability Tester TF165B, 14 months free warranty (12 months normal warranty time + 2 months shipping time).

The test involves immersing coated test panels in water or other liquids, and measuring the rate of water vapor .
water vapour permeability test method
Materials which are able to take in or let out moisture either need to be porous or selectively permeable. Membranes are products which are permeable to low molecular weight products or ions. In this work we will discuss mainly microporous or hydrophilic films, coatings and impregnations, i.e. materials permeable to water vapor.By studying various test methods of water vapor transmission rate, Labthink manufactures many water vapor permeability testers based on ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method) and ISO15106-1/ASTME398 (humidity sensor method). Labthink has the most complete .Water Vapor Permeability Analyzer-W302 /JIS Z0208, Find Details and Price about Water Vapor Transmission Rate Permeability Tester from Water Vapor Permeability Analyzer-W302 /JIS Z0208 - Guang Zhou Biao Ji Packing Equipment Co., Ltd.
By studying various test methods of water vapor transmission rate, Labthink manufactures many water vapor permeability testers based on ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method) and ISO15106-1/ASTME398 (humidity sensor method). Labthink has the most complete .for water vapor it is given in units of mass of water vapor. Sometimes, the amount of permeant is given in moles. Sometimes the term “diffusion coefficient” is used incorrectly instead of permeability, which are different properties, leading to additional confusion. Another complication involves the water vapor transmission rate (WVTR). Cup experiments are the most widely used method to measure the water vapor permeability of porous building materials. For this test, cup assembly is designed to create a vapor pressure gradient across a sample and, thus, to allow vapor diffusion through it. Water vapor permeability is assessed by weighing cup assembly over time.Water Vapor Permeability Tester Lyssy L80-6000 Easy and reliable testing for water vapor permeability. The L80-6000, the latest generation of the proven L80 series, which have been used around the world for decades because it is: • The most cost-effective solution available • Simple to use • Low maintenance • Extremely fast
To determine the resistance of textiles and textile composites (particularly performance wear fabrics) to water vapor penetration. The apparatus consists of 8 containers with water reservoirs, a standard permeable fabric cover, sample holder ring and precision drive system. And its value can be used to estimate the water vapor permeability of the material tested by the following equation: (8) . The modification consists of measuring the total gas pressure in the climatic room and the cup during the test. In this way, the water vapor partial pressure, the total gas pressure, and the water vapor molar ratio can be .By studying various test methods of water vapor transmission rate, Labthink manufactures many water vapor permeability testing instruments based on ASTM E96/GB 1037 (gravimetric method), ISO 15106-2/ASTM F1249 (infrared sensor method), ISO15106-3 (electrolytic sensor method) and ISO15106-1/ASTME398 (humidity sensor method).
