General Introduction
Yokogawa OX400 zirconia oxygen analyzer is a highly accurate and reliable low-concentration type which is capable of measuring a wide range of concentrations, from 0-10ppm up to 0-100vol% O2. Aproprietary new thin-film deposition technology was used in the zirconia sensor that creates a molecular bond between the zirconia element and the platinum layer. This prevents separation, enables a reduction in sensor size and ensures a high-speed response and long life. The OX400 can be used to control and monitor various semiconductor applications, and to control environment, air leakage into inert gas, and other processes.
