Product Introduction

    DBZX-520Y online hydrogen purity analyzer adopts the advanced constant temperature thermal conductivity cell with temperature compensation function from German HLP company. Utilizing embedded microprocessing technology, it overcomes the common drawback of thermal conductivity detectors being affected by temperature, giving the instrument a leading technical advantage. It is an ideal choice for online hydrogen purity detection. This product is widely used in online hydrogen purity detection in hydrogen cooling systems of power plant hydrogen-cooled generator units, hydrogen production stations, petrochemicals, and other industrial hydrogen application fields.
