Scope of Application

【Operating Instructions】

Used to test, evaluate, and grade the dynamic liquid water transmission performance of fabrics. It is based on identifying the water resistance, water repellency, and water absorbency inherent to the fabric's structure, including geometric structure, internal structure, and the wicking characteristics of fibers and yarns.

YG821A Liquid Water Dynamic Transmission Tester

[Scope of Application]Used to test, evaluate, and grade the dynamic liquid water transmission performance of fabrics. It is based on identifying the water resistance, water repellency, and water absorbency inherent to the fabric's structure, including geometric structure, internal structure, and the wicking characteristics of fibers and yarns.

[Compliance Standards]AATCC 195-2011, SN 1689, GB/T 21655.2-2019, etc.

[Product Features]

1. Equipped with an advanced motor control device for precise and stable control.

2. Advanced droplet injection system ensures precise and stable droplet delivery. It features a liquid recovery function to prevent saline crystallization from clogging the infusion pipes.

3. Uses high-quality gold-plated probes with high sensitivity, oxidation resistance, and good stability.

4. Color touch screen display control with Chinese and English interfaces and a menu-style operation mode.

[Technical Specifications]

1. Test Data: Computer-controlled measurement of bottom wetting time, top wetting time, bottom max absorption speed, top max absorption speed, bottom max absorption radius, top max absorption radius, bottom moisture diffusion speed, top moisture diffusion speed, cumulative one-way transport capability, and overall liquid moisture management capability.

2. Liquid Conductivity: 16ms ± 0.2ms

3. Test Liquid Delivery Volume: 0.2±0.01g (or 0.22ml); Test liquid tube inner diameter: 0.5mm

4. Upper/Lower Sensors: 7 test rings, spacing between each ring: 5mm ± 0.05mm

5. Test Rings: Composed of probes; Upper probe diameter: 1.54mm ± 0.02mm, Lower probe diameter: 1.2mm ± 0.02mm

6. Test Time: 120s; Water Inlet Time: 20s

7. Test Head Pressure: <4.65N ± 0.05N (475gf ± 5gf); Data Acquisition Frequency: >10Hz

8. One-touch start: Upon clicking start, the motor automatically drives the test head to the specified position. A built-in pressure detection device stops movement upon reaching the fixed pressure, starts the test, and automatically returns after completion.

9. Equipped with a droplet injection system that is precise and stable. It includes a reverse-pumping system that can rotate in reverse to draw remaining saline from the infusion tube back into the reservoir, preventing pipe blockage due to crystallization.

10. Power Supply: AC 220V, 50Hz, Power: 0.4KW

11. Weight: 30kg
