AUTO W809 Water Vapour Transmission Rate Tester

AUTO W809 Water Vapour Transmission Rate Tester

Manufactured by GBPI Testing Instruments

Adopting internal advanced electromagnetic temperature control technology, the AUTO W809 water vapour permeability analyser uses the gravimetric method to test the water vapour transmission rate of a wide range of materials.

These include fabrics, films, papers, sheets, non-woven fabrics, and related materials in the fields of food, medicine, medical equipment, and daily chemicals.

 

 

Benefits

  • Wide range of high-efficiency water vapour transmission rate testing for low, medium and high water vapour barrier materials.
  • Efficient multi-mode, with an upgraded test cavity and permeable cup design.
  • Fully automatic rotating tray and high weighing efficiency.
  • 360° three-dimensional constant temperature and humidity in the test cavity.
  • Test error is less than 0.05 g/m2·24h.
  • Nine test stations — support weight gain and weight loss test modes.
  • Dual airflow (dry air and wet air) humidity control method and automatic wind speed adjustment for precise control.
  • Humidity accurate to ±2% RH to meet the needs of long-term continuous testing.
  • Power-on self test to avoid testing under fault conditions.
  • Balance thermal insulation and moisture-proof technology ensure the stability and life of the balance.
  • Artistically designed from the perspective of ergonomics and technical aesthetics, with smooth lines and exquisite 3D printed shells.
  • Convenient operation and real-time visualisation of curves.

Applications

Films Water vapour transmittance rate test of film-like materials such as: Various plastic films (PP/PET/PE/PVC/BOPP/CPP, etc.), plastic composite films, paper-plastic composite films, metal composite films, co-extrusion films, aluminised films, degradable packaging films (PLA/PBAT/PBS) etc.).
Sheets Water vapour transmission test of solid pharmaceutical hard sheet (PP/PVC/PTP, etc.), metal composite sheet, rubber sheet, and other sheet materials.
Paper, cardboard and their composites Water vapour transmission test of paper and cardboard such as coated paper, silicone paper, aluminised paper for cigarette packs, paper-aluminium-plastic composite sheet, etc.
Medicinal patches Water vapour transmission performance test of medical plasters.
Packages Customised fixtures can be extended to packaging parts, such as the water vapour transmission rate of medical polyethylene bottles, sealed bags, medical ointment tubes, infusion hoses, plastic trays, etc.
