Product Manual


The OMD-640 oxygen analyzer combines a rugged portable design, integral sample system and updated electronics with SSO2’s precision oxygen sensors. The result is a highly reliable and cost-effective design with easy to use interface.

The analyzer comes with 5 field adjustable ranges: 0 – 1 ppm, 0 – 10 ppm, 0 – 100 ppm, 0 – 1000 ppm and  0 – 25%.  The LDL of the unit on the lowest 0 – 1 ppm is 0.001 ppm.  Custom ranges are available.

The oxygen sensor is based on the galvanic electrochemical fuel cell principal and is manufactured in house under a strict quality procedure.  The sensors are self contained and minimal maintenance is required – no need to clean electrodes or add electrolyte.  The precision sensors offer excellent performance, accuracy and stability while maximizing the expected life.

The analyzer comes with a built in sample system that includes a front accessible sensor housing, a flow control knob, flow indicator and a 4-way bypass valve.  Gas inlet is made via 1/8″ Compression tube fitting.

The electronics are feature packed with an easy-to-use menu interface.  The highlight of the advanced set of electronics include’s a USB output for data logging.  Data logging can be done via a removable USB flash drive and data can be taken in 1 minute intervals.  An 8 GB flash drive can store data for 50+ years.
