Application of Leather Water Vapor Permeability Tester G185

Customer Background

Customer Name: XX International Co., Ltd. (R&D and Quality Control Center)

Industry: Chinese leather footwear and accessories brand, specializing in business formal, casual, and sports-fashion shoes R&D, production, and sales

Core Products: High-end genuine leather shoes, functional outdoor footwear, premium leather goods; positioned as “comfort and breathability.” Products cover 3,000+ stores nationwide and are exported to the EU and Southeast Asia.

Core Pain Points:

Intense comfort competition: High-end market demands extremely high leather breathability. Consumer feedback reported heat and moisture issues; 35% of returns were due to poor breathability.

Inaccurate and unstable test data: Old equipment showed repeatability errors >15% on the same sample, providing unreliable data for new product R&D.

Incomplete standard coverage: EU export required EN ISO 20344, IUP 15, and other standards. Old devices only supported basic domestic methods, unable to generate internationally recognized reports.

Low efficiency, long cycle: Single device had only 2 test stations; one test took 48 hours. R&D batches queued over 7 days, severely delaying product launch.

Manual operation cumbersome: Manual timing, weighing, and recording introduced human errors and made data traceability difficult.

Solution

After multi-brand comparison and on-site verification, the company purchased the G185 Leather Water Vapor Permeability Tester, deploying it in the R&D lab and quality control center to fully replace old devices and establish a standardized water vapor testing system.

Core Advantages of the G185:

Full standard compliance, internationally recognized:

Fully compliant with 12 domestic and international standards including EN ISO 20344, IUP 15, BS 3144, DIN 53333, GB/T 39369. Test data is recognized globally, meeting market entry requirements.

6 parallel test stations, efficiency multiplied:

6 independent stations allow simultaneous testing of 6 samples; rotating table (75±5 r/min) + forced ventilation reduces test cycle to 24 hours, improving efficiency 6×.

Precise and stable, minimal error:

PLC intelligent control + 7-inch touchscreen, automatic timing and stop; precision temperature and airflow control, repeatability error <3%, 98% consistency with third-party results.

Smart operation, traceable data:

One-touch parameter setup, automatic timing/alarm, and automatic data storage; supports historical record query and report export, fully paperless and traceable.

Durable and easy to maintain:

Stainless steel chamber, wear-resistant test bottles, quick-change clamps; annual failure rate <1%, maintenance costs reduced by 70% year-over-year.

Implementation Results

Quality control: Improved breathability, complaints significantly reduced

Leather upper water vapor permeability stabilized at 800–1200 g/(m²·24h) (high-end standard ≥600), improving foot dryness by 40%.

Complaints about “heat and poor breathability” dropped 65%; return rate reduced by 12%.

Internal data fully consistent with third-party results (98% match).

R&D empowerment: Faster product iteration, frequent hits

R&D cycle reduced from 30 days to 14 days; annual new product output increased 50%.

Accurate moisture data optimized tanning and finishing processes, reducing raw material cost by 8% and improving performance by 25%.

Efficiency and cost: Significant savings and productivity gains

Daily testing capacity increased from 2 to 36 samples, eliminating queue bottlenecks.

Reduced outsourcing to third-party labs, saving ~180,000 RMB annually.

Annual maintenance <3,000 RMB; overall device cost down 60%.

Brand competitiveness: “Breathable technology” as core selling point

Accurate test reports enabled successful entry into high-end EU department store channels.
