YY311–Water Vapour Permeation Tester ASTM F 1249 (Infry sensor method)
Determining water vapor permeability characteristics of materials and containers.
Suitable for: Film, sheet, container, and construction material of plastic, textile, leather, and metal.
Laser infrared micro water sensor with wavelength modulation（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 between the two sides of the sample drives the water vapor to penetrate from the high humidity side to the low humidity side. The permeated water vapor is carried to the infrared sensor by flowing dry nitrogen (carrier gas). The sensor measures the water vapor concentration of the carrier gas and calculates the water vapor transmission rate of the sample according to the water vapor concentration of the carrier gas.
YBB 00092003，GB/T 26253，ASTM F1249，ISO 15106-2，TAPPIT557、JIS K7129.
Laser infrared trace water sensor with wavelength modulation. Ultra-long optical path (20m) absorption, high precision.
Automatic attenuation compensation, no need to recalibrate periodically and the data does not decay continuously.
Humidity control ability: 10%~95%RH, 100%RH, fully automatic, fogless.
Temperature control feature: Semiconductor cold and hot bidirectional control, High precision, stable and reliable.
Strong environmental adaptability: Indoor environment, temperature 10 ℃ - 30 ℃, any humidity, low cost of use.
Sample side leakage proof sealing installation technology.
Intelligent and automatic: power-on self-test to avoid test under fault state; one key start, fully automatic test execution.
Software: graphical, the whole process, and all element monitoring; multiple report formats.
Optional: Chinese GMP computerized system function module.
