The SSI oxygen probe has a super-system of high-perbance carbon sensors, through advanced technology to achieve accurate and real-time carbon tracking, always at the forefront of accuracy. The SSI probe series is designed and manufactured in the United States and includes the original Gold probe for use in heat treatment furnaces, the Bazooka probe for endothermic generators and CERAGOLD for harsh industrial environments. A redundant probe system and an independent heating probe system are also provided for use where the oxygen probe can not be installed directly.
