MultiPerm H2O-CO2: H₂O and CO₂ Permeability Tester
SINGLE OR DUAL CELLS
H2O and CO2 Permeability Tester with Integrated Temperature and Relative Humidity Controls.
MultiPerm H2O-CO2: H₂O and CO₂ Permeability Tester
MultiPerm H2O-CO2 is a permeability tester designed to determine water vapor and carbon dioxide transmission through films, barrier materials and multilayer structures.
The instrument measures WVTR (Water Vapor Transmission Rate) and CO₂TR (Carbon Dioxide Transmission Rate) under controlled temperature and relative humidity conditions.
Depending on the model, the one- or two-cell configuration allows testing of one or two samples, either simultaneously or sequentially. MultiPerm H2O-CO2 is suitable for characterizing plastic films, barrier films, laminates, metallized materials and co-extruded structures.
It is designed for research and development, material qualification and quality control laboratories, with applications in the food packaging, beverage, pharmaceutical and electronics industries.
What Does MultiPerm H2O-CO2 Measure?
MultiPerm H2O-CO2 measures the transmission of water vapor and carbon dioxide through packaging materials and barrier films.
- Water vapor transmission rate (WVTR): evaluates the amount of water vapor passing through a material under specified test conditions.
- Carbon dioxide transmission rate (CO₂TR): evaluates the amount of carbon dioxide passing through a material under specified test conditions.
These measurements help characterize material barrier performance and compare different films, laminates and multilayer structures in terms of moisture and carbon dioxide transmission.

Applications of MultiPerm H2O-CO2
Food and Beverage Packaging
WVTR and CO₂TR measurements help evaluate the moisture and carbon dioxide barrier performance of packaging materials and support material selection for food and beverage applications.
Plastic Films and Barrier Materials
The instrument helps characterize plastic and barrier films by measuring their resistance to water vapor and carbon dioxide transmission.
Multilayer Films and Laminates
WVTR and CO₂TR testing supports the evaluation of multilayer structures and laminates designed to provide specific moisture and gas barrier performance.
Pharmaceutical Packaging
Water vapor and carbon dioxide transmission measurements help characterize packaging materials when barrier performance is an important consideration during material qualification.
Containers and Formed Packaging
Permeability testing can support the evaluation of suitable packaging materials and structures, depending on the sample type and available test configuration.
Research, Development and Quality Control
MultiPerm H2O-CO2 can be used in laboratories working on material development, comparative testing, incoming material qualification and quality control.

NORMS: MultiPerm complies with ASTM F2476 for CO2TR measurements and with ASTM F1249, TAPPI T557, JIS K-1729, ISO 15106-2 for WVTR measurements.
MultiPerm is the only instrument on the market with patented technology that allows simultaneous barrier measurements for two different gases on one or two distinct samples. MultiPerm comes equipped with two sensors, which can be selected from oxygen, carbon dioxide, and water vapor.
This instrument is designed to measure the permeability of plastic films, single-layer or multi-layer barrier films, metallized films, or those with special surface coatings, laminated or co-extruded, predominantly used in the food, beverage, pharmaceutical, and electronics industries.
In addition to measuring the permeability of thin films, MultiPerm, equipped with modular accessories, can perform analyses on formed containers such as bag-in-box, PET bottles, and various other receptacles.
MultiPerm represents the ideal solution for companies that produce or utilize barrier packaging, offering the highest performance in a single instrument at a competitive price.
The advanced MultiPerm ExtraSolution® software ensures maximum operational simplicity. Users can start, monitor, and complete the measurements simply by selecting the appropriate tab in the software, which simultaneously and/or sequentially manages the analyses on one or two different samples (depending on whether it is a single or dual-cell model) for two different gases.
Choosing MultiPerm means making an intelligent choice that reduces costs and optimizes space. Why buy two different instruments when you can have everything in one with MultiPerm?
