It can measure concentrations of 10 to 10,000 ppm. Additionally, it can operate at temperatures from 10 to 50C and consumes less than 150 mA at 5V. It also uses SnO2 material, whose conductivity is lower in clean air. Its conductivity increases as the concentration of CO gases increases. Features: High quality double panel
