The SERVOTOUGH Oxy 1900 is a digital oxygen analyzer for hazardous area use.
Offering industry-standard features alongside revolutionary, value-added options, the Oxy 1900 oxygen (O₂) gas analyzer sets new standards of flexibility, stability and reliability from a single, cost-effective unit.
Setting new standards of flexibility, stability and reliability from a single, cost-effective unit, our base configuration model offers all the performance capabilities required for entry-level process oxygen measurements.
For users facing typical process control requirements, our mid-level configuration meets the challenges involved, delivering the same reliable oxygen measurements as the base model, supported by additional automated capabilities and value-added features.
For users who want to get the maximum from their analyser and be ready to meet every eventuality, we offer a full-configuration model for the most demanding process O₂ applications, with all available measurement options fitted.
Adding to our base level configuration build but with the new hydrogen resilient transducer option, this model offers all the performance capabilities required for entry-level process oxygen measurements with sample backgrounds containing hydrogen.
Get a gas analyser ready to meet the specific needs of your unique applications with a user-configured option.
If one of our standard variants doesn’t match your requirements, we offer custom configurations to match your process precisely.

The 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 patented Paramagnetic oxygen sensor, providing highly reliable, accurate and stable percentage measurements of oxygen. Uses industry-leading patented Paramagnetic technology for stable, non-depleting measurement – ensuring a long lifetime of ownership with low maintenance costs.
The Oxy 1900 combines enhanced-safety design aspects with ease of use and installation, creating an analytical solution that can reduce costs dramatically over product life. It offers clever, value-added features including a heated sample compartment for unrivalled measurement stability and simplified sample conditioning systems.
When you work with potentially dangerous, hazardous area applications, you need an O₂ analytical solution that delivers benchmark safety compliance and complete reliability without question; product quality and plant safety depend on the equipment you integrate. The Oxy has IECEx/ATEX/UKEX: for Zone 1, and cCSAus C1, D1 for North America certification and is SIL2 (Route 1H) hardware compliant, ensuring it offers solid, trusted reliability in hazardous area locations.
By utilizing patent Paramagnetic sensing technology, the Oxy 1900 benefits from a stable, accurate measurement that requires minimal calibration. Remote device interaction via digital communication options help to further reduce operational costs.
The Oxy 1900 introduces unique options that offer unrivaled flexibility, operational performance and reduced costs. An innovative heated sample bulkhead, when coupled with the fully heated sample compartment, can reduce the requirement for a gas conditioning system on samples with a dew point of up to 50oC/122oF and also offers excellent measurement stability; a unique FlowCube sensor which guarantees low flow indication during normal operation; and an integrated pressure compensation system compensates for sample pressure variation, enabling tighter process control.
If you’re looking to integrate the Oxy 1900 into your gas analysis system, we can help. Servomex can manage your project from design to installation, with our expertise built into every system. Get in touch to learn more.
