JKGA-801 zirconia oxygen analyzer
JKGA-801 zirconia oxygen analyzer
JKGA-801 zirconia oxygen analyzer is a new type of intelligent industrial grade gas analyzer developed by using imported zirconia sensors, 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 good stability, high reliability and long calibration period;
▌ 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 - automatic switching of percentage range;
▌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, user standard gas online calibration.
Ordering instructions (please indicate when ordering)
▌ the measuring range of the instrument is within 1000ppm of micro oxygen
▌ measured gas pressure: positive pressure, micro positive pressure or micro negative pressure
▌ main components, physical impurities, sulfides, etc. of the tested gas
▌ suction pump can be selected when the measured gas is under micro positive pressure or micro negative pressure
Application area
It is widely used in the measurement of micro oxygen in industrial gases such as petrochemical industry, cryogenic air separation, PSA nitrogen purification unit, high-purity nitrogen, high-purity argon and so on.
