DF-140E Oxygen Analyzer




Superior Oxygen Analysis for Harsh and Hazardous Environments
The DF-140E features:
  • Long term reliability and stability
  • Durability - can be used in Class I, Division 1 or 2 areas
  • Low/No maintenance
  • STAB-ELT option allows for accurate measurement in the presence of acid gases

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.

DF-140E Specifications
Range
  • Ranges are available from 0-10 ppm to 0-25%Sample Gas Compatibility
  • STANDARD 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.)

Options
  • CE Certification
  • Stab-ElT Acid Gas System
  • Oxygen Alarms
  • Sample Pump
  • Flow Alarm
  • Three range
  • Isolated 4-20 mADC output
  • Remote Sensor Heater

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.

Sample Requirements
  • Gas phase, non-condensing, 0░ to 50░ C (32░ to 122░F)
  • Flow should be 1.0 to 3.0 scfh at 0.2 to 1.0 psig pressure.

Misc.
  • 35.6 cm W x 33.5cm H x 29.0cm D 13.6kg. (14.0"W x 13.18"H x 11.42"D 30 lbs.)
  • Operate between 0░ and 45░ C ambient (32░ and 120░ F)
