Aeroqual Sulfur Dioxide (SO2) Sensor Head 0-100 ppm (ESP)

Sulfer Dioxide (SO2) Sensor Head uses Gas Sensitive Electrochemical (GSE) technology to detect Sulfer Dioxide from 0-100 ppm at 0.1 ppm resolution and up to +/-0.5 ppm accuracy.

Back Ordered. Expected to ship on July 30

This Sulfer Dioxide (SO2) Sensor Head uses Gas Sensitive Electrochemical (GSE) technology to detect Sulfer Dioxide from 0-100 ppm at 0.1 ppm resolution with <±0.5 ppm accuracy (in concentrations from 0 - 5 ppm) or  <± 10% accuracy (in concentrations from 5 -100 ppm).

This sensor uses an active sensor technology with an internal fan to pull air across the GSE sensor at a specific flow rate for accurate gas detection.  The fan pulls a stream of air past the sensor every 60 seconds providing a new reading of SO2 levels and a 60 second response time for the sensor.

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 0-100 ppm SO2 head and react accordingly.
