Yokogawa electric production of zirconia oxygen analyzer is widely used in a variety of the combustion monitoring and control process of the industry, and to help industry field has achieved considerable energy saving effect.Application areas including energy consumption industries, such as steel, electric power, petroleum chemical industry, ceramics industry, paper industry, food industry, textile industry, include all sorts of combustion equipment, such as incinerator, middle and small boiler, etc.The analyzer was applied to the combustion monitoring and control, will help full combustion, reducing emissions of CO2, SOx and NOx, and thus contribute to prevent global warming and air pollution.
ZR402G converter with a LCD touch screen, set with a variety of display, calibration, oxygen concentration trend shows that more easy to operate, and shows more enhancements.Converter has all kinds of standard features, such as measuring and computing, as well as the maintenance function, including self-checking.ZR22G points size sensor adopts highly reliable zirconia sensor, the heating equipment can be field replacement.If the sensor is installed in the flue wall, can be directly gas measurement.
