JNL-802B zirconia oxygen analyzer
JNL-802B zirconia oxygen analyzer
JNL-802B zirconia oxygen analyzer is a new intelligent industrial gas analyzer developed by using imported zirconia sensor, special analysis furnace and advanced MCU technology. It has the characteristics of high precision, long life, good stability and repeatability, and is suitable for the on-line measurement of oxygen concentration in various atmospheres.
Product features
▌ the original imported new zirconia sensor is adopted, and the drift is very small;
▌ single point calibration can meet the measurement accuracy of the whole measuring range;
▌ friendly man-machine dialogue menu, easy to operate;
▌ with microprocessor as the core, it has the characteristics of good stability, high reliability and long calibration cycle;
▌ high precision automatic temperature compensation system to eliminate the influence of ambient temperature;
▌ measurement range can be expanded from 0.1ppm to 40.00% o
▌ 1000ppm - percentage range automatic switching;
▌ freely set the upper and lower limit values of the corresponding oxygen concentration of 4-20mA output;
▌ users can get higher precision analog output;
▌ advanced calibration function, online calibration of user standard gas.
