Product details
- Product Name: Water vapor permeability tester (electrolysis method)
- Product Code: W-E-31-M
W-E-31-M
Function
Water vapor permeability performance test.
Films, sheets, boards, containers made of materials such as plastic, fabric, leather, metal, etc.
Working principle
Electrolytic water method.
Nitrogen with a certain humidity flows on one side of the material, while dry nitrogen (carrier gas) flows at a fixed flow rate on the other side; The humidity difference on both sides of the sample drives water vapor to permeate from the high humidity side to the low humidity side of the sample; The permeated water vapor is carried by the flowing dry nitrogen gas (carrier gas) to the electrolytic micro water sensor; The sensor electrolyzes all the moisture in the carrier gas, measures the absolute water content, and calculates parameters such as the water vapor transmission rate of the sample.
Compliant with standards
YBB 00092003，GB/T 21529，ISO 15106-3，DIN 53122-2。
Product Features
