OMD-775 Oxygen Analyzer

The OMD-775 is designed to measure elevated oxygen levels (21% –
100%) for online applications. The unit combines an advanced set of
electronic features with our industry leading precision electrochemical
oxygen sensor technology. The analyzer also has built in temperature and barometric pressure compensation, the result is a highly
reliable and cost effective design with an easy-to-use user interface.
The analyzer comes standard with a 0 – 100% full scale range with
a resolution of 0.01%. The analyzer can also be configured by the
end user in the field for suppressed ranges of 50 – 100%, 80 – 100%
and 90 – 100%. The analyzer comes with the ability to auto-range
through all four ranges, this is accomplished with the choice of a voltage or current analog output.
The analyzer offers the user 2 different digital communication options, both of which are bi-directional. These come in the form of
MODBUS RS485 ASCII or RS232.
Alarm functionality is performed by 2 fully adjustable form C nonlatching relay contacts. These can be configured as NO or NC and
can be set as HIGH or LOW with optional delay mode. A power
failure alarm is also standard and comes as a form C non-latching
relay contact.
The oxygen sensor used in the OMD-775 is based on the galvanic
electrochemical fuel cell principal and is compensated for both pressure and temperature giving the user added accuracy. All oxygen
sensors are manufactured in house by Southland Sensing Ltd. under
a strict quality program.
The analyzer is a cost-effective, yet similarly performing, alternative
to paramagnetic oxygen sensors packaged in a 19” rack mount for
easy installation and operation.
