EcoaZ TB-IIS (Double Unit)

Zirconia Ceramic Type Oxygen Analyzer (Double Unit) for Inert Gas / N2 Generator

"ExxonMobil Recommendations:

All vessels fitted with IGS system MUST have a complete spare IGS oxygen (O2) analyser unit. It is Strongly Preferred that this spare IGS O2 analyser is permanently fitted as an additional IGS O2 analyser to serve as a back-up in case of failure of the main IGS O2 analyser.

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.
