Measurement of oxygen transmission rate, Oxygen Permeation Analyzer 8501 

The 8501 offers a cost-effective solution for accurate, reliable measurement of oxygen transmission rate (OTR) through permeable films.

Laboratory quality analysis of packaging film barriers to give reliable measurement of oxygen transmission rate in a simple to use benchtop system.  This precision oxygen permeation analyzer combines trace oxygen sensitivity, dependability and exceptional ease of use in a compact, single chamber.

The proprietary sensor design allows for extremely fast, accurate results. The 8501 is ideal for high volume production facilities with a purge time of only 30 minutes and test times as short as 20 minutes. With a two button operation it is simple to operate and requires little or no operator training.

This oxgyen permeability instrument is easily calibrated to a certified NAMAS / NIST traceable calibration gas, making the test results traceable to current NAMAS/NIST standards.

Conforms to: ASTM D-3985  ISO 15105-2  DIN 53380  JIS K-7126  F2622-08
