With unsurpassed accuracy, reliability, and flexibility under the most demanding on-line operating conditions, the EC900 process oxygen analyzer is a breath of fresh air.
Brought to you by Systech, our world-leading gas, oxygen and moisture analysis brand, the EC900 series of oxygen analyzers measure levels as low as 20 ppm from ambient air in two minutes!
These highly advanced instruments incorporate user-friendly software and the highest quality sensors to provide accurate, reliable results.
Our oxygen analyzers are designed to monitor oxygen levels within most industrial gasses and atmospheres so operators can maintain controlled environments, protect sensitive processes and ensure consistent product quality. Unaffected by hydrocarbons or volatile atmospheres, our patented sensors are ideal for applications such as wave solder and reflow ovens. Whatever your measuring range, the EC900 series has an oxygen analyzer to suit your needs.
The EC900 helps operators maintain controlled atmospheres, reducing the risk of contamination and protecting sensitive production processes.
With fast response times and reliable measurement across a wide range, it supports consistent product quality in demanding environments.
Long sensor life and low maintenance requirements help reduce downtime and ongoing operational costs.
The EC900 process oxygen analyzer series use a variety of specially engineered electrochemical fuel cells to measure oxygen.
Our RACE™ sensors represent a breakthrough in electrochemical technology – a patented design that prevents saturation from high levels of oxygen.
This helps maintain stable and reliable measurements even when oxygen levels fluctuate, supporting dependable process monitoring.
The EC900 series of Process Oxygen Analyzers are available in a variety of models, depending on if you want your instrument to be bench-top, wall-mounted or integrated into a panel or 19” rack. The sensor/cell type is also configurable for percentage level, trace (ppm) level, ultra-low trace or dual ppm and percentage oxygen measurement.
This flexibility allows the analyzer to be configured to suit different installation environments and oxygen monitoring requirements across industrial processes.

Our oxygen analyzers are used in applications from 20 ppb (parts per billion) up to 100% oxygen. They’re perfect for gas streams such as hydrogen, combustibles, hydrocarbons and inert gasses. With sensors that are easily calibrated to ambient air and traceable calibration gasses – they meet the most demanding quality assurance programs.
This helps maintain accurate oxygen monitoring across critical processes, reducing the risk of contamination, process disruption or product defects.
There’s no need to compromise! Now you can match the sensor to your application for the best possible reliability and performance. All EC900 electrochemical oxygen analyzer sensors are manufactured to rigid tolerances and exacting production specifications.
The EC900 series of process oxygen analyzers feature a bypass flowmeter, a pressure regulator, sample pump and flow alarm.
These integrated components help ensure consistent sampling conditions and dependable measurement performance.
When you invest in an electrochemical oxygen gas analyzer from Systech you get a user-friendly menu with diagnostic capabilities.
Operators can quickly configure measurements and monitor analyzer performance, helping maintain reliable monitoring without complex setup.
The high-tech EC900 series of oxygen analyzers feature fault alarms as standard with high/low alarm options.
These alarms help teams respond quickly to unexpected oxygen level changes and maintain safe operating conditions.
When used in a normal operating range the sensors of our process oxygen analyzers typically last for 3-5 years. To back this up, you’re protected with a three year limited warranty. Your oxygen analyzer is maintenance-free, requires infrequent calibration and there’s no caustic electrolyte to monitor or replace.
This supports long-term reliability while reducing maintenance requirements.
Across the IP portfolio we make a wide range of gas, moisture and oxygen analyzers. From Systech, we also offer the MM500 moisture detector.
Another leading oxygen analysis instrument in the IP family is the Systech OxySense 5250i. It’s an innovative, non-invasive oxygen monitoring system ideal for flexible packaging testing.

Over the decades we’ve learnt a thing or two about monitoring gasses and building exceptional oxygen analyzers. We like to share this knowledge where we can!
For example, we wrote this blog on the types of oxygen analyzers, their uses and functions. Then there’s this piece covering the need for measuring the oxygen transmission rate on PET bottle caps.
Oxygen analyzers work by measuring the paramagnetic properties of the air or gas in an atmosphere. This could be in an open space, like a building or ship, or in a small and enclosed area, like the headspace in an item of flexible packaging. Here are some of the applications our EC900 series of oxygen analyzers are perfect for:
Chemical / petrochemical chemical production
Curing
Electronics
Metals
Pharmaceutical
Process
General
The EC900 series of oxygen analyzers use a variety of electrochemical fuel cells for the detection of oxygen.
When oxygen diffuses to the cathode of the cell, a current output is produced directly proportional to the concentration of oxygen in the sample gas.
Specializing in trace oxygen measurements, Systech’s sensors are used in applications from ppb up to 100% oxygen. In addition, our oxygen analyzers can be used on gas streams such as hydrogen, combustibles, hydrocarbons and inert gasses.
All Systech oxygen analyzers are easily calibrated to ambient air. For ISO purposes and in specific applications, traceable calibration gasses can be used to meet the most demanding quality assurance programmes.
When you enquire about the EC900 Process Oxygen Analyzer, our specialists will work with you to understand your gas composition, measurement range, and installation requirements. We can help you select the most suitable analyzer configuration and provide guidance on delivery timelines and system integration.
