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.
The sensors are self-contained and minimal maintenance is
required - no need to clean electrodes or add electrolyte.
The SSO2 precision oxygen sensors offer excellent perfor
-
mance, accuracy and stability while maximizing the expected
life.
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 calibra
-
tion, or calibrate to a certified span gas to maximize accuracy.
The model OMD-625 oxygen analyzer combines a
rugged design with SSO2’s precision oxygen sen-
sors. The result is a highly reliable and cost effec
-
tive compact design with easy-to-use user interface
designed specifically for the natural gas industry.
The oxygen analyzer is designed to meet standards
for Class 1, Div 1, Groups B, C, D installation.
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 ppm).
