Commodity name: Electrolytic Method Water Vapor Transmission Rate Tester
Commodity ID: W-E-11-A/31-M/71-M /41-F-E

W-E-11-A/31-M/71-M /41-F-E

Function:

Determining water vapor permeability characteristics of materials and container.

Suitable for:

Film, sheet, container and construction material of plastic, textile, leather and metal.

Principle:

Electrolytic detection sensor 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 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.

Standards:

YBB 00092003，GB/T 21529，ISO 15106-3，DIN 53122-2

Characteristics:

●Electrolytic detection sensor, absolute Coulometric sensor
●Ultra high precision, while relative error is stable.
●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, whole process and all element monitoring; multiple report formats.
●Optional: software module of Chinese GMP computerized system.。
