ASTM D3241-17a

Revolutionary ellipsometric jet fuel thermal oxidation heater tube scanner. Our new OptiReader provides pass/fail results with a full 2D and 3D thickness map defining maximum deposit thickness and volume. Results are not only fast, but also highly precise and accurate. The user interface is so simple it doesn't require any training which saves time and money.

OptiReader's accurate and fast results, and data integration capabilities make it the best heater tube tester in its class.

OptiReader is now cited as an approved procedure in ASTM D3241-17a (Thermal Oxidation Stability of Aviation Fuels Test Method)
