JNL-600 thermal conductivity analyzer
JNL-600 thermal conductivity analyzer
JNL-600 thermal conductivity analyzer is a new type of intelligent industrial gas analyzer developed by using imported thermal conductivity sensor and advanced MCU technology after being packaged in specific environment. It is suitable for on-line measurement of hydrogen, carbon dioxide, argon and helium in various atmospheres.
Product features
▌ the original imported thermal conductivity 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;
▌ advanced calibration function, user standard gas online calibration;
▌ suitable for measuring helium, hydrogen, argon and carbon dioxide;
▌ the upper and lower limit alarm points can be set arbitrarily in the full range.
