I. Composition:

LRD-SZO series Zirconia Oxygen Analyzer is a complete set of instruments that includes a zirconia oxygen sensor, oxygen transmitter, and remote display.

II. Application
LRD-SZO SeriesZirconia Oxygen Content AnalyzerRapid and accurate on-line detection and analysis of flue gas content during the combustion process of boilers, kilns, heating furnaces, and other combustion equipment to achieve low-oxygen combustion control, energy conservation, and reduce environmental pollution.
LRD-SZO SeriesZirconia Oxygen Content AnalyzerConsists of two parts: zirconium oxide heads (primary instrument) and oxygen content transmitters (secondary instrument).
The LRD-SZO type zirconia probe housing is made of high-temperature and corrosion-resistant stainless steel material. No additional gas is required.
The reference gas can self-convection. It is equipped with a standard gas interface, which allows for calibration and verification using standard gases during on-site operation. The probe zirconium tube can be easily removed and replaced.
The LRD-SZO oxygen transmitter features a simple structure, standardized installation dimensions, reasonable wiring design, advanced manufacturing quality, stable and reliable instrument performance, and easy debugging.
LRD-SZO SeriesZirconia Oxygen Content AnalyzerDue to its superior performance-to-price ratio, it has been widely used in large and medium-sized power plants domestically for several years.
