JZrO series zirconia oxygen analyzerDetailed product description：

purpose
The JZRO series zirconia oxygen analyzer is suitable for continuous monitoring of oxygen content in industrial furnace flue gas. It serves as a basis for operators to adjust the combustion air ratio or is connected to the automatic control system to achieve low oxygen and reasonable combustion, reduce fuel consumption, stabilize processes, improve product quality, and reduce environmental pollution. It has significant economic and social benefits.

Product Features
The probe is manufactured using nanotechnology, with a resolution of one hundred thousandth, short response time, excellent seismic and erosion resistance, and a long service life of the probe.
The oxygen electrode adopts pure platinum electrode, which effectively improves the electrical performance and activity of the probe.
Adopting high-temperature metal mesh filters overcomes the disadvantages of low penetration rate, easy blockage, poor thermal conductivity, and inconvenient cleaning of conventional ceramic filters.
The converter adopts a 16 bit processor and a fully isolated signal circuit. The menu style operation interface can provide standard 4-20mA corresponding outputs, upper and lower limit node outputs, RS485 communication, and convenient calibration operations for controlled temperature, oxygen content, oxygen potential, output, range, and nodes. The unique three parameter calibration of oxygen content can more accurately reflect the oxygen content at commonly used operating points.
The separately equipped heating transformer can significantly improve the service life and temperature control accuracy of the probe heating furnace.
The zirconia oxygen probe adopts active assembly, and the internal accessories can be replaced separately. Users may replace the oxygen sensor, electric furnace, thermocouple and other components separately.
