Product Details

Product Name: Infrared water vapor transmittance tester
Product Code: W-IR-11-A

W-IR-11-A

Function

Water vapor permeability performance test.

Films, sheets, boards, containers made of materials such as plastic, fabric, leather, metal, etc.

W-IR-11-A

Working principle

Wavelength modulated laser infrared micro water sensor (TDLAS).

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 infrared sensor; Sensors measure the concentration of water vapor in the carrier gas; Calculate parameters such as water vapor permeability of the sample based on the concentration of water vapor in the carrier gas.

Compliant with standards

YBB 00092003，GB/T 26253，ASTM F1249，ISO 15106-2，TAPPI T557、JIS K7129。
