Oxygen probe SS27/MS27

industrialzirconia

General Information Potentiometric oxygen probes developed for the exhaust gas measurements in motor vehicles (λ-probes) are frequently used in industrial equipment. Due to their construction, these probes have some disadvantages: because of the uncontrolled heating (steady working voltage) and ceramic coating of the electrodes (which increase the diffusion of special gas components) significant measuring errors can result. The ZIROX miniature probes MS27 and SS27 with controlled heater and integrated primary electronics provide high precision at comparatively lower costs. The main part is the approved ZIROX potentiometric zirconia based solid electrolyte cell (drift-, calibration- and maintenance-free). The use of high quality components and materials guarantees a high long-term stability. The SS27 was developed for trace measurements under oxidizing conditions. The MS27 was constructed for reducing conditions or oxygen concentration of more than 100 ppm. Both probe types only differ in the type of sensor element. Applications Oxygen measurements in protective gases Exhaust gas measurements in large-scale engines Control optimization in small combustion plants Furnace gas measurements in heat treatment equipment Optimisation of incineration plants Monitozing of industrial processes under protective or inert gas atmosphere
