China Water Vapor Transmission Tester ULB-T09 - Quality Fabrics Supplier & Factory for Moisture Management Solutions
Application
Feature
-
1.
Fabric Water-vapour Transmission Tester Apply to various standards and testing methods.
-
2.
Rotary specimen holder, the speed can be adjusted. The test is much evenly than fixed specimen holder.
-
3.
The wind speed can be adjusted. Adopt import air velocity transducer to demarcate which can ensure the speed.
-
4.
The temperature and humidity control use RID algorithm, which fluctuation is small and can prevent the overshoot. The temperature and humidity calibration function can avoid the sensor bias caused by long time using.
-
5.
Textile Water Vapour Permeability Tester high accuracy temperature and humidity sensor makes the test result reliable and precise.
-
6.
Single chip control, color touchscreen operation, modular design, temperature and humidity digital setting, intelligent control and real-time display the temperature, humidity and time.
-
7.
Can input parameter on the touch screen and calculate the WVT, WVP, PV value.
-
8.
The water vapour transmission rate tester equipped with upper computer software, can record the temperature and humidity curve, be easy to calculate and print mass data report.

Frequently Asked Questions
What materials can be tested using the Fabric Water-vapour Transmission Tester?
The tester is designed to evaluate the water vapour transmission of various fabrics, including moisture-permeable fabrics, and non-woven materials such as bat wool, space cotton, and sportswear fabrics.
Which international testing standards does this equipment comply with?
It meets multiple major testing standards, including GB/T12704, GB/T21655, ASTM E90, ASTM E96, JIS L1099, and BS 7209.
What are the primary differences between Model ULB-T09-1 and ULB-T09-2?
The main differences lie in the capacity, dimensions, and weight. Model ULB-T09-1 has 1 layer with 8 cups, while Model ULB-T09-2 features 2 layers with 8 cups per layer (totaling 16 cups) for higher throughput testing.
How does the tester ensure stable temperature and humidity control?
The system utilizes a PID (RID) control algorithm to minimize fluctuations and prevent temperature/humidity overshoot. It also features a calibration function to correct sensor bias over long-term usage.
Does the tester support data export and curve analysis?
Yes, the tester is equipped with upper computer software that can record temperature and humidity curves, calculate WVT, WVP, and PV values, and print comprehensive mass data reports.
