Rain Tester - lab instrument
Standard
AATCC 35: Water Resistance: Rain Test for Fabrics
BS EN ISO 22958: Textiles – Determination of Resistance to Water Penetration – Rain Test
GB/T 23321: Textiles – Testing and Evaluation for Water Repellency
Product Advantages
Realistic Simulation: Mimics horizontal rainfall (60–240 cm water column) to evaluate fabric water repellency under dynamic conditions.
Precision Control: PLC + touchscreen automation ensures stable water pressure (±1.5 cm accuracy) and liquid level consistency.
Versatile Testing: Suitable for umbrellas, raincoats, protective clothing, and industrial composites.
Data Accuracy: Measures absorbent paper weight gain post-test for quantitative water repellency analysis.
Energy Efficient: 1000W heating system maintains water temperature (±1°C uniformity).
User-Friendly Design: Large reservoir (40L) reduces refill frequency; tap/distilled water compatible.
Product Features
Horizontal Spray System: 13 nozzles (φ0.99mm) simulate directional rainfall at 305mm from the sample.
Adjustable Water Column: 60–150 cm (standard) or 60–240 cm (extended) pressure range.
Stainless Steel Construction: Corrosion-resistant inner groove for vertical sample fixation.
Automated Replenishment: Algorithm maintains constant water level for consistent pressure.
Sample Compatibility: Fits 40mm × 285mm × 190mm material sizes (e.g., fabrics, laminates).
Safety & Compliance: Overheat protection, emergency stop, and CE certification.
