DX-SZO series zirconia oxygen analyzer is a combination of zirconia oxygen detector, oxygen transmitter, remote display and other supporting instruments
可对锅炉、窑炉、加热炉等燃烧设备在燃烧过程中所产生的烟气含量进行快速、正确的在线检测分析，以实现低氧燃烧控制，达到节能目的，减少环境污染。 The DX-SZO series zirconia oxygen analyzer can quickly and accurately detect and analyze the flue gas content generated by combustion equipment such as boilers, kilns, heating furnaces in the combustion process, in order to achieve low-oxygen combustion control and achieve energy savings. Purpose to reduce environmental pollution.
有氧化锆头（一次仪表）和氧量变送器（二次仪表）二部分组成。 The DX-SZO series zirconia oxygen analyzer consists of a zirconia head (primary meter) and an oxygen transmitter (secondary meter).
DX-SZO zirconia probe housing is made of high temperature and corrosion resistant stainless steel. No external gas is required, the reference gas can convection on its own. It is also equipped with a standard gas interface, which can be calibrated and verified with standard gas during field operation. The probe zirconium tube can be easily removed and replaced.
The DX-SZO oxygen transmitter has a simple structure, standard installation dimensions, reasonable circuit design, advanced process quality, stable and reliable instrument performance, and convenient debugging.
由于其优越的性能价格比，数年来在国内大中型电厂得到广泛应用。 DX-SZO series zirconia oxygen analyzer has been widely used in domestic large and medium-sized power plants for several years due to its superior performance-price ratio .
