W303 2.0 Water Vapour Transmission Rate Tester
Manufactured by GBPI Testing Instruments
The W303 2.0 is based on the gravimetric method of water vapour permeability. This involves measuring the weight change of a material as it absorbs or desorbs water vapour.
This instrument is suitable for measuring the water permeability performance of films, sheets, papers, packaging, and other related materials in industries such as food, daily chemicals, medical equipment, pharmaceutical, and photovoltaic electronics.

Benefits
- High-precision weighing sensor offers high weighing efficiency and stable performance, with a resolution up to 0.0001 g/(m2 ·24h).
- Semiconductor stabilise automatically controls the temperature, with a temperature control accuracy of ±0.1°C.
- Adheres to ASTM E96/E96M and ASTM D1653 standards (For full list see Specifications).
- Three chambers with independent data meet the requirements of high throughput testing and testing efficiency is high.
- Wide measuring range of 0.1~10000 g/(m2 ·24h) meets the testing demand of high, medium, and low barrier materials.
- Using customised fixtures enables you to measure the the water vapour transmission of bottles, bags, bowls, and other packaging parts.
- Designed from the angle of ergonomics to provide easy operation and an exquisite 3D printed shell.
- Automatic operation, one key test, automatic judgment, and automatic shutdown.
- Real-time curves display of transmittance: Time, temperature-time, humidity-time, weight-time.
| 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 rate 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 patch | Water vapour transmission performance test of medical plasters. |
| Package | 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. |
