The Nova 412 Series O2 analyzers utilize a magneto-dynamic paramagnetic measuring cell and powerful selenium cobalt magnet assembly with on-board pre-amplification to provide the highest standard of O2 analysis. Accuracy is further augmented by built-in barometric pressure compensation and detector temperature control. For high purity applications ( Model 412HP) , a high resolution digital readout is added.
