DF-140E
Reliable, Accurate Oxygen Sensor in a Nema
4x Enclosure
Superior Oxygen Analysis for Harsh and Hazardous
Environments
The DF-140E features:
- Long term reliability and stability
- Durability – can be used in Class
I, Division 1 or 2 areas
- Low/No maintenance
- STAB-EL™ option allows for accurate
measurement in the presence of acid gases
The DF-140E allows for reliable oxygen measurement
in a wide variety of environments, including outdoors and in explosive
environments with a NEMA 7 remote sensor enclosure. Using the revolutionary
non-depleting E-Sensor, the DF-140E delivers reliable readings without
frequent recalibration and periodic sensor replacement.
