- Double Unit, selectable between 2 Oxygen Analyzer
Daiichi Nekken is a Zirconia Electrochemical Type Oxygen Analyzer. It can indicate oxygen concentration in gas continuously. The EcoaZ TB-IIS consists of the sensor and control unit. The control unit indicates an oxygen concentration. The sensor detects the oxygen concentration. Both are connected with the signal cable.
Daiichi Oxygen Analyzer is using Zirconia Ceramic sensing cell. The Zirconia Ceramic works under the high temperature more than about 600°C and becomes able to move in stabilized zirconia.
