GPR-3500MO Oxygen Analyzer
Developed for measuring 0-100% oxygen in general purpose areas, features barometric pressure and temperature compensation
Suitable for trace oxygen measurements from 0.1 ppm through to purity applications at 100% oxygen, these rugged portable instruments share the same advanced sensor technology as the online process oxygen analyzers ensuring confidence in their reliability and accuracy.
The Analytical Instruments concept of using the same HMI and menu structures for portable and online analyzers makes it extremely easy for operators to use both types of instruments on their site without need for extra training.
