Oxygen Instruments, Analysers and Sensors for Precision Measurements

Process Sensing Technologies (PST) supplies oxygen and gas measuring systems for healthcare environments.

48 Lancaster Way Business Park,
Ely, Cambridgeshire CB6 3NW,
United Kingdom

Process Sensing Technologies (PST) designs and manufactures medical-grade oxygen and gas measuring systems, which are critical for monitoring and analysing gases used in healthcare environments. The company consists of a group of established brands, including Analytical Industries, SST Sensing, Ntron and Michell Instruments.

Our sensors and analysers provide reliable and accurate measurement of oxygen, carbon monoxide and carbon dioxide channelled through a hospital or facility’s medical gas piping network or anywhere a medical gas outlet is available. These gases must be controlled strictly to comply with current operating standards.

We can also provide customised medical sensors for healthcare original equipment manufacturers (OEMs) tailored to individual designs and specifications.

PST provides a full range of sensors for major ventilator and respirator brands.
Our AII-2000 and AII-2000 Palm O2 gas analysers are used to verify oxygen and other medical gases in clinics.
PST Zirconium Dioxide Sensors measure ambient gas using a unique closed-loop measurement system.
Our LuminOx optical oxygen sensors measure oxygen levels using luminescence-based optical technology.
The Microx Oxygen Analyser uses zirconia or electrochemical technology to give accurate and reliable oxygen concentration measurements.
PST's MoGas93 medical gas analyser is designed for generation systems producing oxygen at 93% volume.
The Senz-Tx Oxygen Transmitter monitors oxygen in gas generation and glove boxes reliably and cost-effectively.
Our MDM300 sensors offer spot-check measurements of dew point or moisture content for a range of applications.

Oxygen ventilator solutions for medical device manufacturers

Process Sensing Technologies offers a number of solutions for oxygen ventilator manufacturers and a wide range of sensors for oxygen leak detection. Oxygen ventilator manufacturers must ensure that medical devices are safe for patient use and comply with standards for the safety and essential performance of medical electrical equipment.

Our oxygen sensors and gas analysers are approved by the US Food and Drug Administration (FDA) and designed with decades of experience supplying solutions for critical healthcare applications. Every sensor is put through a rigorous inspection programme and its details are logged in our central database.

PST’s range of sensors for oxygen ventilators complies with the IEC60601-1 standard. Many of our sensors are already used by established ventilator manufacturer brands.

Gas measurement solutions for medical applications

Process Sensing Technologies provides oxygen sensors for monitoring gas concentration, gas quality, hospital gas control systems and ambient oxygen environments. Technological advances in air separation have resulted in an increase in demand for oxygen generators in medical and industrial markets.

On-site gas generation provides a cost-effective and safe alternative to traditional cylinder or liquid-type nitrogen and oxygen supply. Pressure swing adsorption (PSA) technology has also led to the creation of generators that can supply high-quality medical-use oxygen at source.

Monitors for incubators and glove boxes

Process Sensing Technologies offers a range of gas monitoring instruments suitable for use in medical and laboratory environments such as incubators and glove boxes.

Incubator sensors allow the user to control carbon dioxide, relative humidity, temperature and pH at constant levels. They are designed to mimic a cell’s natural environment and ensure that conditions remain constant.

Our range of sensors for glove box applications includes trace moisture transmitters and oxygen transmitters suitable for various conditions and situations. The sensor exchange programme for moisture and oxygen transmitters ensures that maintenance is quick, simple and causes minimal disruption and downtime.

For more complex glove box applications that require multiple trace impurities to be analysed, PST’s integrated online trace impurity analysers, gas stream selection and gas purifiers provide complete, affordable and reliable turnkey systems.

Custom oxygen sensor technologies for medical applications

Process Sensing Technologies offers a range of sensor technologies, including optical, zirconia and electrochemical sensors. Our industry experts can help you decide which technology is most suited to your medical application based on your requirements.

Our oxygen sensors are designed for advanced life support systems used in intensive care and emergency medical environments. They can also be used for respiratory treatments, anaesthesia, incubators, lung function and ventilation technology.

PST analysers and sensors can be used for a wide range of applications: inerting reactors or vessels; argon, helium or nitrogen purity; natural gas and biogas monitoring; combustion control on boilers and incinerators; cylinder filling and bottling plants; marine inert gas generation; carbon dioxide purity in breweries; and annealing furnaces.

Our devices are designed to meet the rigorous demands of healthcare and provide long-term stability at a reasonable price.
