How long do sensors last on air monitors?
A. The life of a sensor depends on several factors; mainly how frequent it has been exposed to a gas, the concentration of the gas it’s been exposed to, if the monitor has suffered a blow and if has been exposed to any poisonous vapors such as volatile organic compounds (VOCs) or Freon. Even when the monitor is turned off, the sensor can still deplete if it is exposed to its respective gas. To extend the life of the sensors, you can either store the monitor in an air tight container or remove the sensor from the monitor entirely and store it in an air tight container like a camera film jar. Removing the sensors for an extended period of time will in most cases require the user to recalibrate them. When used and stored correctly, oxygen sensors will have an average life of 1-2 years, where toxic and LEL sensors will have an average life of 2-4 years.
