AQ Sensors vs Instruments 2B TecHnologies
Sensors tend to respond linearly over only one to two orders of magnitude, compared to approximately five order of magnitude for the measurement of ozone by UV absorbance, for example. However, the lack of a wide dynamic range is seldom a serious limitation for AQ sensors since the concentration range of interest is not that wide.
Gas Sensors Ozone
Ozone concentration gradients are common in rooms and are greatly influence by air movement and eddy currents. This effect will be more pronounced at concentrations less than 100 PPB. Monitor Design and Use. Aeroqual’s ozone monitors are designed with "active sampling" to maximize air sampling at the sensor (to minimize ozone losses).
