Page 8: Area Of Application
The measuring system is used to continuously measure the oxygen concentration in furnace atmospheres, flue and process gases or vacuum systems. The SS27 probe was designed for measuring the oxygen concentration in furnace atmospheres and process gases. Due to its open design, it reacts quickly and can cover a wide measuring range from 1 vol.-ppm to 20.64 vol.-% O... -
