The OMD-625 is a cost-effective online intrinsically safe instrument for measuring oxygen continuously with very little maintenance requirements.  The analyzer is designed for use in Class 1, Division 1 groups B, C, D.  Primary applications for this analyzer include natural gas, landfill, hydrogen production and other industrial applications.


The electronics are highly reliable and feature packed with a very easy-to-use MENU interface.  No need to lug an expensive laptop into the field to configure the unit. Electronic features include 4 – 20mA or 1 – 5 VDC, 2 alarm relay contacts, multiple ranges and a 12 – 24VDC power input.

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 multiple ranges from 0 – 1 PPM up to 0 – 100%.  Optional sensors can be configured for PPM or Percent oxygen analysis, sensors designed for Inert, CO2 or H2S background gases applications.

If you need help configuring the analyzer for your application, please contact our technical sales team.
