YMKE200-B portable oxygen analysis Features: 1. Imported sensor can measure trace oxygen, constant oxygen, high purity oxygen, with fast response, high measurement accuracy, long calibration period and weak acid resistance; 2. Using a unique protective gas path to effectively protect the sensor and prevent the sensor from affecting the life of the sensor due to prolonged exposure to the air; 3. Built-in sensor protection device and temperature compensation sensor ensure the service life of the sensor and reduce the influence of sample temperature and environmental changes on measurement accuracy; 4. Powered by a large-capacity lithium battery, the continuous measurement time is not less than 8 hours. 5. Automatic data storage function, users can access historical data at any time; embedded installation, easy to install and maintain.
