High reliability trace and percent Oxygen measurements in pure and multi-gas backgrounds, designed for division 2/zone 2 hazardous area locations




Sensing Technology


Designed for use in harsh and hazardous areas, the DF-320E is designed to provide trace and percent level Omeasurements in Division 2 / Zone 2 hazard-rated locations. Servomex’s reliable Coulometric sensing delivers highly stable measurements in changing sample and flow rate conditions, making it ideal for upset prone processes.

The reliability and resilience of the DF-320E makes it the ideal analytical solution for applications including hydrogen, propene and polyethylene production, oil refining and petrochemical process monitoring.

In addition to providing the ultra-reliable performance demanded by these applications, the DF-320E offers attractive cost savings over product life, thanks to its factory calibrated Coulometric sensing technology, which simplifies setup. Ongoing maintenance is also reduced to annual SPAN calibrations, with no need for programmable cell replacement.
