What is an Oxygen Depletion Sensor?
Technically, all oxygen sensors are oxygen depletion sensors. The term "oxygen depletion" is associated with lower levels of oxygen, than what a human would require for healthy breathing. The "sensor" is the device that measures the oxygen levels.
To make the device useful, the oxygen depletion sensor may be in the form of a handheld personal safety device, a wall-mounted fixed alarm, packaged with batteries, or with industry standard outputs for controlling other machinery and manufacturing processes.
Whether you are in cryogenics, a chemical treatment plant, automotive, or safety industries, being able to readily monitor Oxygen depletion is crucial.
Oxygen as many people know it, is a substantial part of life, yet we can not see, smell or taste the gas and at hazardous levels - it is dangerous.
By protecting individuals, customers and establishments, oxygen depletion sensors can become integral and life-saving for a variety of establishments.
Oxygen Depletion Sensor Modules
One of the most common uses of an oxygen depletion sensor is found in safety industries. In these environments there are specific regulations around the gas and the need to measure oxygen in confined spaces is necessary. These modules are utilized in any place where low oxygen levels can be present.
A common example is in a setting where pressurized cylinders of hydrogen, argon, or nitrogen may be stored or produced. If one of these areas experiences a leak, the oxygen levels in an enclosed area could be fatal.
Due to injuries around hazardous O2 levels, many regulations have been put in place to prevent injury and tragedies from occurring. The Occupational Safety and Health Administration for example states in the "Permit Required for Confined Spaces" that the standard is for any oxygen deficient atmosphere containing less than 19.5% O2, is hazardous and may not be entered by non protected workers.
GasLab Oxygen Depletion Sensors
We carry a wide variety of electrochemical oxygen depletion sensors, which are easy to use, highly accurate and durable; dependent upon your overall application. These sensors also can measure from 0 to 100% volume of oxygen, making them extremely useful for measuring oxygen depletion, or oxygen enrichment.
Engineers, scientists and researchers all continue to stand by our sensing solutions and technologies due to their unique design, pre-calibration testing and effectiveness in inert atmospheres.
We have highlighted the most common oxygen depletion sensors below,
- Alphasense O2-A2 Oxygen Sensor - is able to accurately and reliably measure up to 21% of oxygen levels by volume. Used in laboratory, cryogenic and scientific environments.
- Alphasense O2-A3 Oxygen Sensor - is designed for low oxygen safety applications and does not require power, yet generates micro-amperes proportional to the ambient oxygen level.
- Luminox LOX-02 25% Oxygen Flow Through Sensor - measures ambient oxygen levels using the principle of fluorescence quenching by oxygen. This sensor module includes a tube-cap adapter for closed-system oxygen measurement. Utilized in many medical and scientific environments.
- Luminox LOX-02 25% Oxygen Sensor - measures ambient oxygen levels and provides benefits of lower power requirements and a longer lifespan.
- Oxygen Depletion Safety Alarm - the RAD-0002 or oxygen depletion safety alarm monitors indoor oxygen levels near storage tanks of gases like carbon dioxide, nitrogen, or argon.
- Personal Oxygen Safety Monitors - the personal oxygen safety monitors or (SAN-20 and SAN-102) are wearable, personal, oxygen safety devices; that allow for consistent monitoring and measurement while ensuring workers are out of harms way.
- Oxy-Flex Oxygen Analyzer - the Oxy-Flex Analyzer is suitable for measuring oxygen levels in closed systems such as ventilation pipes and boiler exhaust flues. It can measure the oxygen concentration in air or gas mixtures with temperatures of -100 to 400⁰C.
- Tecpen Handheld Oxygen Sensor - the TecPen is designed to provide accurate oxygen level measurements in closed and pierceable packaging. Found most commonly in Modified Atmospheric Packaging, food processing and pharmaceutical applications.
Oxygen Depletion Sensor Applications
Oxygen depletion sensor tools can be integrated into a vast range of environments to date. One environment that is found prevalent today for utilizing and measuring levels of oxygen is cryogenics.
Cryogenics involves dealing directly with the effects of different materials at very low temperatures. Liquid nitrogen for example, is a gas in which plays a large role in cryogenics as it is most commonly used to achieve low temperatures, yet can be extremely hazardous if not properly monitored. With the growing popularity of cryogenics and cryotherapy, there is now a direct need for oxygen safety devices to protect individuals in the workplace.
Another common environment is the medical and research industries. Many of our customers use oxygen for a variety of scientific experiments and when working in a research lab, one may encounter different types of gas depending on the research or course of study.
Oxygen sensors can be crucial to keeping scientists and researchers out of danger and harms way.
These sensors are also used in oxygen analyzers which are seen in many medical applications and environments. Anesthesia monitors, respirators, and drug containers all require oxygen control. Surgical procedures also require oxygen sensors to play a large role when it comes to monitoring patients. Lastly, incubators also utilize oxygen to help curate growth and development, and assist in maintaining the overall pH levels.
A unique oxygen application that is continuing to rise just this year, is the use of oxygen monitoring in Modified Atmospheric Packaging or "MAP".
Modified Atmospheric Packaging is used primarily in the food production process, and uses an optimal blend of pure oxygen, carbon dioxide and nitrogen within a high barrier to carefully control perishability in food packaging.
If the contents in a package are getting too much oxygen, they will start to expire much faster and monitoring oxygen levels can ensure the food item is up to industry standard.
Too much oxygen however, like any other application, requires proper oxygen measurement and monitoring tools.
Overall, oxygen depletion sensors and tools are vital for human safety and for anyone working in and around inert gases such as nitrogen, argon or helium. Regardless of your environment, GasLab's oxygen depletion sensors can provide best-in-class solutions and safety for you and your employees.
