LFY-214 Fabric Surface Water Resistance (Dampness Absorption) Testing Instrument

Main purpose
Used to measure the water resistance (dripping) of the surface of fabrics that have undergone or have not undergone water-resistant or water-repellent treatment.
Instrument features
Install the sample on the clamp and make it at a 45° angle to the horizontal. The nozzle sprays water at a certain distance onto the sample. Compare the appearance of the sample with the evaluation standards and the reference sheet to determine its dripping grade. Technical Specifications
1. Nozzle: 19 holes (uniformly distributed)
2. Hole diameter: Φ0.9mm
3. Spray length: 150mm
4. Spray time: 25s - 30s
5. Spray volume: 250ml distilled water
6. Dimensions: 260mm × 260mm × 510mm
7. Weight: Approximately 2kg
