S E R V O T O U G H DF-340E
HIGH-SENSITIVITY TRACE/
PERCENT COULOMETRIC
OXYGEN ANALYZER CERTIFIED
FOR HAZARDOUS AREA USE
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.

SUPPORTING
The SERVOPRO range makes Servomex’s reliable, stable
and accurate gas measurements available to a diverse
range of safe area applications.
An extensive range of non-depleting Servomex gas sensing
technologies – including Paramagnetic, Zirconium Oxide,
Thermal Conductivity, Plasma and Gas Chromatography
– are integrated into flexible analyzers that either meet
specific measurement requirements, such as for syngas,
hydrocarbons or trace gas mixtures, or provide multi-
gas monitoring capabilities for applications including
air separation unit (ASU) production and continuous
emissions monitoring (CEMS).
PROCESS
Designed for benchtop use, or mounting in a 19” rack,
all SERVOPRO analyzers feature extensive functionality,
remote communication options and can be operated
directly via intuitive onboard software.
