The SI-AQ VOC Monitor is the ideal instrument for you should your specific application require testing for Volatile Organic Compounds (VOCs) or potentially harmful gasses such as Carbon Monoxide (CO). In addition, the (Si-VOC) Si-AQ VOC Monitor can an also be outfitted with up to three (3) Gases sensors in total among VOC, CO2, CO, Formaldehyde, NO2, NO, O2, SO2 & H2S in addition to measuring Relative Humidity, Ambient Temperature and Barometric Pressure.
