JKGA-600-Ar thermal conductivity analyzer

JKGA-600-Ar thermal conductivity analyzer

JKGA-600-Ar thermal conductivity analyzer is a new type of intelligent industrial gas analyzer developed by using imported thermal conductivity sensors and advanced MCU technology after being packaged in a specific environment. It has the characteristics of high precision, long life, good stability and repeatability, and is suitable for on-line measurement of argon concentration in various atmosphere environments.

Product features  

▌ Chinese and English menu switching function, intuitive and convenient operation;

▌ imported thermal conductivity sensor is adopted, which has the characteristics of fast response, high measurement accuracy, long calibration period and weak acid resistance;

▌ the unique protective gas path is adopted to effectively protect the sensor, so as to avoid the sensor's long-term exposure to the air that may affect the sensor's life;

▌ built in sensor protection device and temperature compensation sensor ensure the service life of the sensor and reduce the impact of sample gas temperature and environment changes on the measurement accuracy;

▌ the calibration in the whole range is simple and convenient;

▌ data automatic storage function, users can look up historical data at any time and locally; embedded installation, easy installation and maintenance;

▌ when the measured gas is atmospheric pressure or micro negative pressure, it can be equipped with built-in suction pump. The air pump is a fully imported part with long stable performance and long service life.
