OMD-625 Oxygen Analyzer | Product Specifications

Oxygen Analyzer:

The model OMD-625 oxygen analyzer combines a rugged design with SSO2’s precision oxygen sensors. The result is a highly reliable and cost effective compact design with easy-to-use user interface designed specifically for the natural gas industry.

The oxygen analyzer is certified for use in Zone 1 IIB + H2 applications.

The oxygen analyzer is isolated both on the power input and analog output. This eliminates most electronic gremlins seen with existing competitive equipment in the field.

Standard ranges include 0 – 10ppm, 0 – 100ppm, 0 – 1000ppm, 0 – 10000ppm, 0 – 25%.

Optional Percent Analysis Ranges: 0 – 1%, 0 – 5%, 0 – 10%, 0 – 25%, 0 – 100%.

Custom Range: The unit comes with the ability to customize a 6th range (i.e. 0 – 94.0 ppm).

Exigences d'alimentation :

Input Power: 12 – 24 V DC
Current Draw: 50 mA

Oxygen Sensor Technology:

The oxygen sensor used in the OMD-625 is based on the galvanic electrochemical fuel cell principal. All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict quality program.

The standard cells are unaffected by other background gases such as H2, He or Hydrocarbons. The acidic cells work well when acid gases such as CO2 or natural gas are present. H2S resistant sensors are available for sour gas streams with <500 PPM H2S.

Les capteurs sont autonomes et nécessitent un entretien minimal. Il n'est pas nécessaire de nettoyer les électrodes ni d'ajouter un électrolyte.

The SSO2 precision oxygen sensors offer excellent performance, accuracy and stability while maximizing the expected life.

Oxygen Sensors:

TO2-133 PPM Oxygen Sensor: Trace Analysis, Standard
TO2-233 PPM Oxygen Sensor: Trace Analysis, Acidic
TO2-238 PPM Oxygen Sensor: Trace Analysis, < 500PPM H2S
PO2-160 Percent Oxygen Sensor: Percent Analysis, Standard
PO2-24 Percent Oxygen Sensor: Percent Analysis, Acidic

Oxygen sensors should be periodically calibrated. Factory recommendation is every 2 – 3 months or as the application dictates. Sensors offer excellent linearity with an air calibration, or calibrate to a certified span gas to maximize accuracy.
