PureAire oxygen deficiency monitors and analyzers can be used for nitrogen, argon, helium. Carbon dioxide can be detected with the dual O2/CO2 monitor.

Most gas detection companies use oxygen sensors with an electrochemical sensor or fuel cell. These sensors are built to operate for 1 to 2 years and are designed to be thrown away at the end of their lifespan. In fact, fuel cells have a shelf life. These products do not offer long-term solutions for companies.

In contrast, PureAire uses a proprietary zirconium sensor, which is a solid-electrolyte based technology that is designed to last for 10 years with no replacement. Zirconium sensors use direct electrical current rather than battery technology, which is how electrochemical sensors operate.

This unique construction makes PureAire’s sensors the most accurate, reliable and long-lasting products on the market.

PureAire’s sensors are designed to last for at least 10 years with no replacement required. Often sensors work much longer. In fact, some of our first customers who started using PureAire products in 1997 report that their sensors are still working.

If you use an oxygen monitor with an electrochemical type sensor, which is most oxygen sensors on the market, then you will need to replace your sensor every one to two years. Electrochemical or fuel-type sensor are like a battery and over time begin to lose their responsiveness. To operate accurately, and keep the facility safe, electrochemical sensors must be calibrated frequently.

No PureAire products use electrochemical or fuel cell sensors, so if you are using one of our products, you will not need to replace the sensor for at least 10 years.

When you switch to a zirconium sensor from PureAire, you’ll save time and money. Our sensors need no maintenance or calibration to work properly, which means better protection for your facility.

If you are using an electrochemical sensor, you will need to calibrate the unit every 2 to 3 months and replace the unit every year or every other year.

PureAire oxygen sensors do not require the typical calibration like the electrochemical sensors, and they last significantly longer than other O2 monitors to save you thousands over the lifetime of the unit.

PureAire’s sensors calibrate themselves through a unique process, where the sensor is exposed to 99.9 percent nitrogen, known concentration, or oxygen reducing gas which pushes the level below 20.9 percent before it quickly recovers. This happens with no trigger from you. However, you should check the sensors every 6 or 12 months to verify that the unit is working properly. Verification is easy and instructions are provided with every sensor. If your sensor needs an adjustment, you can use the menu under the settings to do so.
