Ozone (O3) sensor head. Gas Sensitive Semiconductor (GSS) head will measure Ozone gas from 0-0.15 ppm with a 0.001 ppm resolution.  This is the perfect head for measuring low levels of ozone up to 0.15 ppm.  The OZU head will allow ozone gas measurements at very low levels, and a 0.001 ppm resolution without the expense of an expensive ozone analyzer.

This sensor uses an active sensor technology with an internal fan to pull air across the GSS sensor at a specific flow rate for accurate gas detection.  This fan will pull a fresh gas stream across the GSS sensor every 60 seconds for accurate Ozone detection in most every environment.

This sensor head will be a direct fit onto any Series-200, Series-300, or Series-500 Aeroqual ozone monitor.  This head can be purchased as an addition to your existing monitor, or with a new base unit.  To purchase with a base unit see our Aeroqual ozone monitor page.  If you currently have an Aeroqual ozone monitor this sensor will be a direct fit for your current monitor.  The Series-200, Series-300, or Series-500 will automatically detect this as a 0-10 ppm Chlorine head and react accordingly.
