The award-winning Oxy 1900 sets the standard for O2 gas analysis, delivering a feature-rich solution designed to meet the monitoring needs of even the most challenging applications. 

At the heart of the Oxy 1900 is Servomex’s patent Paramagnetic oxygen sensor. Providing highly reliable, accurate and stable percentage measurements of oxygen. The non-depleting technology requires minimal calibration and never needs replacing - ensuring a long lifetime of ownership with low maintenance costs. 

This analyzer combines enhanced-safety design aspects with ease of use and installation, creating an analytical solution that can reduce costs dramatically over product life. With clever, value-added features including a heated sample compartment for unrivalled measurement stability and simplified sampling, the Oxy 1900 leads the market and sets the standard for hazardous area Omonitoring.
