Targeted VOC measurements are useful in controlled environments ( labs, research) where the target compound is used and process control or health and safety risks are required. To measure a targeted VOC, a known correction factor is applied to calculate the relative value from isobutylene that is used for the sensor calibration. However, to avoid a cross interference no other VOCs should ...

A VOC sensor (volatile organic compounds) measures volatile organic compounds in the air in general. It reacts to a variety of different pollutants at the same time. It is useful as a pure indicator (whether the air is polluted by something), but it does not give an exact CO 2 reading. With regard to NDIR sensors, there are two types ...

VOC sensor: Alternatively, many volatile organic compound (VOC) sensors are often used to measure CO 2. Through a complex formula, the results are calculated based on the presence of VOC’s in the air. This option is often preferred if a device does not have space or means to install a sensor that is specifically designed to measure CO 2. Chemical carbon dioxide sensors: Chemical carbon ...

With the Eurotronic Air Quality Sensor and a ZWave gateway, you can easily monitor VOC levels to ensure a healthy indoor environment at all times. CO2. Every person constantly emits CO2 when breathing. Too high CO2 concentration leads to headaches, loss of concentration as well as reduced performance. With the Eurotronic Air quality sensor and ...

Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a ''true'' CO2 sensor ...
