Accurate Sensors

Accurate Sensors

N/A The OX-TRAN® 1/50 uses our reliable Coulometric sensor that requires no calibration and complies with the ASTM standard D3985.

The Permatran-W® 1/50 G uses our reliable RH sensor for accurate transmission rate readings that complies with the ASTM standard E398.

Efficient Use of Space

Efficient Use of Space

N/A The upright design and compact footprint require less lab space than many other permeation instruments. It’s completely integrated control system with display makes it a perfect standalone instrument.

Applications

Applications

N/A The 1/50 Series are designed to be an effective yet simple-to-use instrument for a wide range of applications where low throughput is acceptable. The testing capability make them an ideal WVTR instrument to test single samples from mono-layer to multi-layer films, coated films and coated paper board. Whether it is research and development at a university, or as a QC instrument to support production operations it provides reliable data to support your permeation testing needs.

    Basic Permeation Instrument

    Basic Permeation Instrument

    N/A The 1/50 series Instruments are designed to be easy to use and provides reliable accurate test results. They are a cost-effective option for laboratories looking to start in-house permeation testing.

    Simple Operation

    Simple Operation

    N/A The easy-to-read digital display has advisory prompts for inputs to step operators through the requirements to set up and run a test. Advanced users can enter individual test parameters via the key pad, then run the test and/or save it as a method or Quick Start for use by other operators. This reduces the training needed to achieve reliable and repeatable test results. Press the Quick Start button to initiate a fully automated test following stored parameters, thus reducing operator variability. Final test reports can be printed with the optional printer. The keypad is easy to learn and use while the automated testing provides consistent results and fewer potential errors.

    Ease of Loading

    Ease of Loading

    N/A These instruments feature our exclusive test cell drawer design with one horizontal removable easy-to-load test cartridge that improves test repeatability. A single button opens and closes the drawers, and the cartridge is automatically clamped in place with consistent and even force on any sample thickness. This approach provides greater test repeatability than manual or cam clamping methods. With the cartridge removed, it is easy to clean and consistently load samples on the bench-top, reducing operator variability.
