This is really dependent on the specific sensor as each may have a different storage life.  For a general rule, we like to store our acid electrolyte sensors for a maximum of 3 months (for use [...]

Calibration is recommended by using a certified span gas in the range of analysis. We recommend sourcing an O2 mixture that falls into the 80 – 100% of the range you are using. Calibration should [...]

The maximum load is a flat 10K, however no load is recommended. It is also worthwhile to note that the sensors cannot handle a reverse current flow.

Moisture does not damage the sensor, however build up of excess moisture can block the gas flow. Another issue to monitor is that moisture and other types of corrosive liquids can damage the [...]

Temperature influences the signal output at the rate of 2.54% per °C. Compensation is recommended.

All sensors are rated at 0°C (32°F) to 50°C (122°F)

CO2 and H2S gas can have an adverse effect on the life of our oxygen sensors. If you have an application that might contain CO2 or H2S, please contact a sales representative and ask for our [...]

The main difference between the two measurement ranges is the amount of oxygen present. One can easily convert back and forth between the two, 20.9% is equal to 209,000 ppm of oxygen. PPM or [...]

The sensors are electrochemical devices which generate a current signal output (typically uA) that is proportional to the amount of oxygen present in the application. When no oxygen is present, [...]
