The DF-140E allows for reliable oxygen measurement in a wide variety of environments, including outdoors in a NEMA 4x enclosure and in explosive environments with a NEMA 7 remote sensor enclosure.

Using highly stable Coulometric sensing technology, the DF-140E delivers reliable readings without frequent recalibration and periodic sensor replacement. It is specifically designed for reactor process control, pressure wing absorber nitrogen skids, and blanketing and inerting applications. With the STAB-EL system option it neutralizes trace contaminants, enabling accurate measurement in the presence of acid gases.

Thanks to its flexible and reliable measuring response, the DF-140E offers considerable cost savings over its product life, and can be configured as a single range or three-range analyzer to meet specific application requirements.
