The main purpose
LFY-216S Plastic Film Moisture Permeability Tester uses a moisture-permeable cup moisture absorption method to measure the ability of water vapor to pass through plastic film packaging.
Instrument characteristics
1. The instrument main cabinet and instrument control cabinet with refrigeration system.
2. Use a special moisture-permeable cup, which fully complies with the GB/T 1037-1988 standard.
3. With PID self-tuning temperature/humidity controller, the wind speed is adjustable.
4. Digital display timer.
5. Start timing button/stop timing button.
