ZOC zirconia oxygen analyzer is a new oxygen measuring instruments, has a unique two-parameter correction, power can be provided through the instrument parameters, the error correction detection probe, thus ensuring rapid and accurate measurement. It is not only to reduce environmental pollution, energy conservation, improve the combustion efficiency play an active role, and project management and quality control as an important means, in power, petrochemical, metallurgy, fertilizer and other industrial boilers, boiler areas of life are widely used. 
 A full set of instruments measuring the oxygen sensor into the transmitter and the two parts of zirconia. 
 Transmitter by the oxygen transmitter, temperature control system and operation display parts. Oxygen transmitter output 0 ~ 10mA or 4 ~ 20mA two linear constant current signal for the recorder or computer use. Temperature control circuit to the probe heated to 700 ℃, to ensure that the probe work. Display section to display the transmitter from the school, the measured oxygen value, the temperature of the probe and the probe output signal and other parameters. 
 Zirconia sensor: stainless steel structure, demolition of Zirconia exchange convenience, without external suction pump, the reference gas convection, and equipped with standard air interface, can be easily calibrated line to ensure the accuracy of measurement. 
 Equipped with RS485 communication port, Modbus communication protocol.
