How often do you need to replace sensors?

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.
