Oxygen Analyzing Products:

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.

Accuracy (at constant temperature)

Greater of ±3% of reading or 0.5% of range

Response Time

Responds instantaneously to O2 change. Equilibrium depends on specific conditions. Typically <10 seconds to read 90% of a step change.
