Cost-Effective Measurement Solutions Designed for the Most Demanding Applications and Critical Industries

There is significant performance and quality differences between manufacturers of automobiles, computers, and yes, gas analyzers and monitors too. Having served the industrial marketplace for over 25 years, the products manufactured by Alpha Omega Instruments continue to pass the test of time in terms of performance and reliability. 

We have decades of product knowledge and application experience to guide customers quickly and efficiently through the product selection process.  Our quality products fit a variety of mission critical applications for safety monitoring and process monitoring.

Our process analyzers, both trace and percent oxygen analyzers and transmitters, and oxygen deficiency safety monitors are used globally in commercial, government, and educational institutions.

If you are concerned over unsafe levels of oxygen explore a complete line of oxygen deficiency monitors. Our portfolio of Alpha Omega Instruments trace and percent oxygen analyzers and transmitters, safety monitors (oxygen deficiency) and moisture monitors and cost-effective and reliable.  We supply many instruments to medical, aerospace, and municipalities.

Our products serve the petrochemical, energy, refining, bulk gas, aerospace, energy, environmental, food and beverage, atmospheric, biofuels, oil and gas, pharmaceuticals, chemical, pulp and paper, water and wastewater, semiconductor, laboratory and research, life science, atmospheric, aerospace, pharmaceuticals, biotechnology, and medical markets.

With our Series 1300, our proprietary Enhanced Electrolyte System (EES) extends the life expectancy of the sensor to years instead of approximately 12 months typical of most “fuel cell type” sensors.  

The OXY-SEN™ Oxygen Monitor is an economical percent oxygen monitoring system equipped with a standard measuring range of 0-100%.  It comes standard with dual 4-20 mADC recorder outputs that are scaled over 0-100% and 0-25% and can operate in harsh atmospheres.  If you need a fast monitor, the OXY-SEN responds instantaneously to changes in O2.

The Series 2000 Percent Oxygen Analyzer is a rugged, microprocessor-controlled percent oxygen analyzer with either single range or three range capabilities from 0-1 to 0-100%.  It has a high tolerance for gases containing up to 100% carbon dioxide.
