MultiPerm O2-H2O: O₂ and H₂O Permeability Tester
Single or Dual Cells
O2 and H2O Permeability Tester with Integrated Temperature and Relative Humidity Controls.
MultiPerm O2-H2O: O₂ and H₂O Permeability Tester
MultiPerm O2-H2O is a permeability tester designed to determine oxygen and water vapor transmission through films, barrier materials and multilayer structures.
The instrument measures OTR (Oxygen Transmission Rate) and WVTR (Water Vapor 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 O2-H2O 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, particularly in the food packaging, beverage, pharmaceutical and electronics industries.
What Does MultiPerm O2-H2O Measure?
MultiPerm O2-H2O measures the transmission of oxygen and water vapor through packaging materials and barrier films.
- Oxygen transmission rate (OTR): evaluates the amount of oxygen passing through a material under specified test conditions.
- Water vapor transmission rate (WVTR): evaluates the amount of water vapor passing through a material under specified test conditions.
These measurements help characterize the barrier performance of materials and compare films, laminates and multilayer structures in terms of oxygen and moisture transmission.

Materials That Can Be Tested
MultiPerm O2-H2O can be used to characterize different types of materials, including:
- Plastic films
- Barrier films
- Multilayer films and laminates
- Metallized films
- Co-extruded structures
- Flexible packaging materials
The instrument supports material characterization and comparison during development, qualification and quality control activities.
Applications of MultiPerm O2-H2O
Food and Beverage Packaging
OTR and WVTR measurements help evaluate the oxygen and moisture 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 oxygen and water vapor transmission.
Multilayer Films and Laminates
OTR and WVTR testing supports the evaluation of multilayer structures and laminates designed to provide specific oxygen and moisture barrier performance.
Pharmaceutical Packaging
Gas and water vapor transmission measurements help characterize packaging materials when oxygen and moisture protection are important considerations in material qualification.
Research, Development and Quality Control
MultiPerm O2-H2O can be used in laboratories working on material development, comparative testing, incoming material qualification and quality control.

NORMS: MultiPerm complies with DIN 53380-3, ASTM D3985, F2622, F1927, F1307, JIS K-7126, ISO 15105-2 for OTR measurements, and 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?
