- 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.
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。
