S E R V O T O U G H DF-140E
RELIABLE RESULTS IN A TESTING
RANGE OF ENVIRONMENTS
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.

SENSING TECHNOLOGY
Coulometric sensor delivers accurate results
with no sensor drifting, false low readings, or
frequent calibration requirements
Designed for heated or external locations, the
DF-340E remains stable in changing sample and
flow rate conditions, and is designed to provide
measurements of trace or percent level oxygen
in pure gas streams and multi-gas backgrounds.
It is ideal for upset prone conditions.
