JNL-500B micro oxygen analyzer

JNL-500B micro oxygen analyzer is a new type of intelligent industrial gas analyzer developed by using imported fuel cell sensors and advanced MCU technology. It has the characteristics of high precision, long life, good stability and repeatability, and is suitable for on-line measurement of trace oxygen concentration in various atmosphere environments.

Product features  

▌ original imported fuel cell sensor is adopted, with minimal drift;

▌ 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;

▌ advanced calibration function, user standard gas online calibration;

▌ suitable for the measurement of trace oxygen in nitrogen, hydrogen, argon and reducing gas;

▌ the upper and lower limit alarm points can be set arbitrarily in the full range.

Ordering instructions (please indicate when ordering)
