Flue oxygen analyzer has a variety of fault information prompting functions. Self-contained fault detection function can improve troubleshooting efficiency and self-protection ability. PID automatic temperature control circuit, fast and accurate heating, can eliminate the influence of external environment on temperature control. With its own fault detection function, it can improve the efficiency of troubleshooting and self-protection ability.
Flue oxygen analyzer main features:
1.High-bright OLED active light display, intuitive display;
2.The new zirconia sensor has extremely small drift, fast response and high precision.
3. Add coating on the pipe wall of the sensor contacting the flue gas to reduce the corrosion of the sensor caused by the corrosive gas and extend the service life;
4.The contact part of the oxygen probe and the flue gas adopts a new high-temperature alloy steel, and the oxygen probe can be directly inserted into the furnace chamber below 650℃;
5.Two-point calibration can meet the measurement accuracy of the entire range;
6.The probe and meter are IP54 protection class (except he probe front end);
7.Users can freely set the 4-20mA (default) or 0-10V (optional) output corresponding to the upper and lower limit value, so that users can get higher precision analog output;
8.Standard RS232 (default) or RS485 (optional) communication interface for two-way communication with a computer or other digital communication device.
