JNL-2100L portable high-purity on-line oxygen analyzer

JNL-2100L portable high-purity on-line oxygen analyzer is a new type of intelligent industrial grade gas analyzer developed by using imported ion current sensor and advanced MCU technology. It has the characteristics of high precision, long life, good stability and repeatability. It is suitable for on-line measurement of oxygen concentration in a wide range of atmospheres.

Product features

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

▌ it adopts the imported ion current sensor, 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 life being affected due to long-term exposure to the air;

▌ 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 check historical data locally at any time; embedded installation, easy installation and maintenance;

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

Ordering instructions (please indicate when ordering)
