JNL-802Q zirconia oxygen analyzer

JNL-802Q zirconia oxygen analyzer adopts imported zirconia sensor and advanced MCU technology to develop a new intelligent industrial gas analyzer. 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.
