AUTO W812 Water Vapour Transmission Rate Tester
Manufactured by GBPI Testing Instruments
The AUTO W812 moisture vapour transmission rate tester uses the cup method to test the rate of water vapour transmission of films, sheets, papers, fabrics, non-woven fabrics, etc. The cup method is considered the simplest and most widely used method for determining water vapour transmission properties.
Engineered for high efficiency, this instrument has a newly designed test cavity and breathable cup design, with the ability to connect it to the Internet of Things (IOT) platform to realise network digital management.
The AUTO W812 Water Vapour Permeability Analyser offers a broad spectrum of water vapor transmission rate detection, catering to low, medium, and high water vapour barrier materials in various applications such as food, medicine, medical equipment, and daily chemicals. These include:
Films | Water vapour transmittance test of various plastic films (PP/PET/PE/PVC/BOPP/CPP, etc.), plastic composite films, paper-plastic composite films, metal composite films, co-extrusion films, aluminium 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, aluminium paper for cigarette packs, paper-aluminium-plastic composite sheet, etc. |
Medicinal patches | Water vapour transmission performance test of medical plasters. |
Packages | Customisable clamps can be extended to packaging parts, such as medical polyethylene bottles, sealed bags, medical ointment tubes, infusion hoses, and plastic trays. |
