Description

The PERMATRAN-W 3/34 high-tech analyzers can test the Water Vapor Transmission Rate (WVTR) on both films and packages from low to high barriers. They feature 2 independent cells with interchangeable horizontal test cartridges that allow a wide variety of sample sizes and types to be easily and accurately tested.

 

Highest Accuracy

  • MOCON’s patented modulated infrared sensor is the only modulated sensor system on market meeting ASTM F1249
  • Low detection levels down to 0.005 g/(m2 x day)
  • Fully automated temperature, flow and RH controls simplify testing and provide unparalleled repeatability

Best Throughput

  • Industries fastest sensor response time allows shorter overall test times
  • Removable test cartridges allow fast easy sample preparation
  • Automated test method can start a test by a single press of a button
  • TruSeal gas flushed perimeter sealing can eliminate the need for absolute zero in many tests thus shortening overall test times

The PERMATRAN-W 3/34 WVTR analyzer is easy to use and offers the shortest test times available in the market. It uses the MOCON’s patented long life modulated IR sensor which is the basis for the ASTM standard F1249.

MODELS:

This family of highly accurate instruments has 2 models each having a different factor of lower detection limits.

  • H Model (common barriers) – the most popular detection range from 0.05 to 100 g/(m2 x day)
  • G Model (high barriers) – is able to achieve a factor of 10 lower than the H Model providing a range from 0.005 to 100 g/(m2 x day)

 

The upper detection limit can be extended with the use the reduced area film test cartridge (factor x9), or various size masking.

 

The series has industry leading features such as removable and interchangeable horizontal test cartridges, easy to use touch screen operator interface, and fully automated testing providing higher throughput in the lab with less training.

 

For more than 25 years, MOCON’s PERMATRAN series of instruments have been the most trusted and longest lasting on the market. From simple single layered barriers to complex multi-layered barriers, the PERMATRAN-W 3/34 is the right choice for reliable WVTR testing.

Test Methodology

Following ASTM F1249

Standard Test Method for Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor

Summary of Test Method

A dry chamber is separated from a wet chamber of known temperature and humidity by the barrier material to be tested. The dry chamber and the wet chamber make up a diffusion cell in which the test film is sealed. Water vapor diffusing through the film mixes with the gas in the dry chamber and is carried to a pressure-modulated infrared sensor. This sensor measures the fraction of infrared energy absorbed by the water vapor and produces an electrical signal, the amplitude of which is proportional to water vapor concentration. The amplitude of the electrical signal produced by the test film is then compared to the signal produced by measurement of a calibration film of known water vapor transmission rate. This information is then used to calculate the rate at which moisture is transmitted through the material being tested.
