How to Recalibrate the TVOC Sensor

Resetting your devices VOC sensor

Element's TVOC readings are relative to its environment and the sensor calibrates as such. When a device is moved to a new environment it needs to calibrate to that space. This can mean that two different devices that have been measuring different environments can have different readings when moved to the same space. To create consistency the TVOC sensor needs to be recalibrated, this can now be done in the app. To get the most accurate readings we recommend recalibrating to a fresh air environment. Depending on weather and location availability, this can mean recalibrating the device when it’s placed in a windowsill or just any well-ventilated space.

-Please move the device to a location that has a lot of fresh air, we recommend a windowsill. Make sure that the device is plugged in and connected to your wifi. If you are calibrating more than one device we advise that you do this process at the same time in the same space. When all these steps are completed select next

-This process will take 2-3 hours for a full fresh air recalibration. Please verify that you can leave the devices in their present location for that amount of time and then click Next to recalibrate

-You will then receive this slide that confirms the calibration is in progress

-When looking at your devices readings you will be able to see that the calibration is still in progress by the little cog icon next to the TVOC readings
