Reflow Oxygen Analyzer WZ-200D with 128x64 Dot Matrix LCD Display Measuring Range 0~25.00% and Lowest Measurement 1ppm

• Product Features:
Imported double zirconia sensor, high measurement accuracy, fast response, calibration
Long cycle and other characteristics;
It can work in the air for a long time without affecting the life of the sensor;
Fast response speed, the lowest measurement 1ppm;
Wide range AC power supply, wider application range;
Any point calibration can meet the measurement accuracy of the entire range, making the calibration simple and convenient: built-in temperature automatic compensation function, reduce the impact of temperature changes on the measurement accuracy: no reference gas, not affected by the oxygen concentration of the working environment;
Friendly man-machine dialogue menu, intuitive and convenient operation;
Can be one-way or two-way communication with the host computer;
Built-in original imported sampling pump, and through the software can set the working mode of the pump.
