Water Vapor Permeability Tester TT-WVP-100

Water Vapor Permeability Tester TT-WVP-100 measures the water vapor transmission rate (WVTR) of packaging material. This instrument is widely used in food industry, pharmaceutical industry, cosmetics flexible packaging materials industry(plastic film, barrier materials, sheets, metal aluminum, PVC,PVC sheets), college, university and quality institution for their water vapor transmission rate(WVTR) test and quality control.

It carries the standards of ASTM E96-00e1, ASTM D1653-03, TAPPI T464, ISO2528.

Water Vapor Permeability Tester TT-WVP-100 has designed with the principle of weighting method to use weight reduction method to test the water transmittance rate (WVTR) of plastic films. Namely in the regulated temperature, relative humidity conditions, the sample two sides keep the vapor different pressure, measuring the vapor volume passed through, figure out the WVTR value. Unit is g/ m2·24h.

Water Vapor Permeability Tester TT-WVP-200

The Water Vapor Permeability Tester TT-WVP-200 has two test chambers with two separate sensors, and is a self standing instrument. TT-WVP-200 gives simultaneous test reports, as both the test chambers have separate sensor. It measures trace water vapor transmission rates in packaging barrier films. It can precisely control the temperature and simulate the humidity. The dual-testing mode (increasing and decreasing weight methods) is initially adopted. Testing curve could spontaneously show the permeation, temperature, humidity and the weight of water permeating cup. It also features auto-judging, auto-outage, and auto-storage of the data’s.
