With double the number of cells and expanded measurement capabilities, the Si-CA 230 is suited to the most powerful industrial machines. And with support for more gases and a high CO tolerance threshold, its versatility makes it the ideal choice across residential, commercial and industrial applications. 

Up to six gas sensors
Total NOx & Low NOx Capable
Field Replaceable Pre-Calibrated Sensors
Large Color Touch Screen
iOS and Android Mobile Apps for Real-Time Display & Control
CO Dilution auto-range with measurements to 50,000 ppm
