The ZR22G is a robust oxygen detector that uses a long-life zirconia sensor to measure oxygen concentrations directly in process gases. It is designed to be installed directly into stacks or furnace walls, eliminating the need for sampling systems and reducing maintenance requirements.
The ZR802G is an advanced converter that processes signals from the ZR22G detector. It has a digital display that shows oxygen concentration, cell temperature and cell EMF. With a user-friendly touch screen interface (HMI), the ZR802G facilitates easy operation and configuration.
Together, the ZR22G and ZR802G offer a reliable solution for monitoring oxygen and moisture levels in combustion gases from small and large boilers, industrial furnaces and other combustion plants. They are also suitable for controlling low-oxygen combustion and monitoring humidity in drying processes using electric heaters or hot gas as a heat source.
