Yokogawa electric machine production of oxygen analyzer is widely used in a variety of the combustion monitoring and control of the industry, and has made considerable achievements in energy saving.These industries include energy consumption industries, such as steel, electric power, petroleum chemical industry, ceramics industry, paper industry, food processing industry, textile industry.In the incinerator, middle and small boiler combustion equipment a variety of application of the oxygen analyzer, helps to burn fully, and reduce the emissions of CO2, SOx, NOx, which contribute to prevent global warming and air pollution.
Integrating sensor and converter ZR202G oxygen analyzer without any sampling system.Probe can be directly inserted into the flue or furnace, measurement of oxygen content in flue gas under 700 ℃.
The probe assembly on the highly reliable zirconia sensor and field replacement heater.The use of infrared switch, so you don't need to open the case at the scene also can realize to the operation of the instrument.Automatic calibration unit to realize automatic calibration.
ZR202G is large or small boiler and various kinds of industrial furnace, combustion equipment testing oxygen content and achieve the best choice for low oxygen combustion.
features
To reduce the installation cost
The infrared switch control
Zirconia sensor and heater device can field replacement
To measure oxygen concentration and moisture
Using a digital communications (HART) for remote maintenance and reduced maintenance costs
Description: HART is the HART communication foundation, a registered trademark.
