    Product introduction

    It is used to measure the oxygen content in the flue gas of various boilers and industrial kilns to guide the correct operation of boiler operators. The boiler is operating under optimized combustion conditions, and the oxygen content can also be transmitted and output to the control system to achieve closed-loop control, in order to achieve the best results of energy saving and environmental protection.The detection probe is oxidation error.
