DF-310E Flexible, Adaptable Oxygen Analyzer

The DF-310E with the E-Sensor is ready to handle your oxygen analysis needs in almost any application.

The DF-310E features:
  • Accuracy - the greater of ±3 reading or ±0.02% range
  • Ranges from 0-0.5ppm to 25%
  • Instantaneous response to oxygen change
  • Fast response - typically less than 10 seconds to read 90% of a step change
  • Background gas compatibility including N2, H2, Co, freons, hydrocarbons, and more
  • STAB-ELT option removes acids and ionic impurities from the electrolyte that could affect sensor performance
  • Optional battery back-up for extended use and process protection

  • Ranges are available from 0-50 ppm to 0-25%

Sample Gas Compatibility
  • BASIC SENSOR: All inert and passive gases including N2, CO, H2, Ar, freons, hydrocarbons, etc.
  • SENSOR WITH Stab-ElT OPTION: Neutralizes trace contaminants including acids such as CO2, H2S, NOX, SOX, etc. (Consult Delta F for concentration limits.)

  • Stab-ElTAcid Gas System
  • Sample Pump
  • Oxygen Alarms
  • Flow Alarm
  • Isolated 4-20 and 2-20 mADC outputs
  • NEMA 4X and 7 Sensor Enclosures
  • Remote Sensor Heater
  • Battery Backup

Accuracy (at constant temperature)
  • Standard Resolution Sensor: Greater of ±3% of reading or 0.5% of range
  • High Resolution Sensor: Greater of ±3% of reading or 0.02% of range (except for ranges <100 ppm: ±3% of reading or ±0.05% of range)

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

Sample Requirements
  • Gas phase, non-condensing, 0° to 50° C (32° to 122° F)
  • Flow from 1.0 to 3.0 scfh at 0.2 to 1.0 psig pressure (except 15-25 psig for 310E H0050 without pump)

  • 21.1cm W x 19.7cm H x 20.1cm D 4.52 kg. (8.32"W x 7.75"H x 7.91"D 10 lbs.)
  • Operate between 0° and 45° C ambient (32° and 120° F)
  • Input Power: 24 VDC, 1 Amp (max)
