Original Yokogawa Single Channel Zirconia Oxygen/Humidity Analyzer Zr22g Zr802g
This analyzer consists basically of a probe and a converter that are used as both a Zirconia Oxygen Analyzer and High Temperature Humidity Analyzer.
The ZR802G converter uses a digital display, displays the cell temperature and cell emf in addition to the oxygen concentration and includes a Human Machine Interface (HMI), that offers easy touch screen operation. This analyzer is most suitable for monitoring the oxygen concentration of combustion gases in large or small boilers, various industrial furnace and combustion devices, or for the control of low-oxygen combustion.
Separate type Zirconia High Temperature Humidity Analyzers are used to measure the humidity of hot gases continuously in driers which use an electrical heater or hot gas as the heat source. They can also be used in a variety of manufacturing applications in humidifiers, as well as in driers, for humidity measurement and control. They can help improve productivity in these application fields.
