Instrument Features:
a. Friendly man-machine dialogue menu, intuitive and convenient operation; b. 320×240 graphic dot matrix color LCD display, the display is delicate and clear; c. Adopt original imported double zirconia sensor, which has the characteristics of high measurement accuracy, fast response speed and long calibration period; d. Gas circuit blockage alarm and self-protection function, the sampling pump will be automatically shut down in case of gas circuit failure, effectively extending the sampling pump e. Real-time test data can be displayed in the form of data or curve; f. 40,000 historical data storage, which can be viewed locally in the form of a list or curve, or exported through the serial port; g. The instrument supports multiple Point piecewise linear calibration to meet the accurate measurement of oxygen content in the full range; h. Automatic temperature compensation function to eliminate the influence of temperature changes on measurement accuracy; i. Built-in imported sampling pump, long life and reliable work; j. Wide range AC power supply, wider application range; k. According to user needs, optional RS232 (default) or RS485 data communication interface can be used for direct one-way or two-way communication with computer or other digital communication equipment. |
