Tips: How Often Should A CO2 Sensor Be Calibrated?

The more accurate the CO2 reading required, the more often it should be calibrated. However, CO2 sensor staff typically recommends customers to place their sensors or devices on a regular calibration cycle like their important devices and equipment.

For specific industries we recommend the following calibration cycles and methods:

• Scientific Experimentation – zero calibration before each test
• Safety – zero calibration at least annually
• Beverage/ Restaurant - zero with nitrogen at least annually
• Greenhouse – zero with nitrogen after each growing cycle
• Manufacturing – zero with nitrogen at least annually
• Indoor Air Quality – ABC or fresh air as desired
