Product Introduction

    DBZX-110 multi-channel hydrogen leakage monitoring system consists of a monitoring host and detection transmitters. The monitoring host adopts an embedded system to achieve centralized control of multiple monitoring points, directly displaying multiple hydrogen concentrations and alarm statuses. When the hydrogen concentration reaches the preset alarm value, the system will issue an alarm signal to prompt safety measures and prevent safety accidents. This product is widely used for online monitoring of hydrogen leakage in hydrogen production stations of power plants, enclosed busbars, neutral points, turbine ends, excitation ends, oil return systems, and inner cooling water tanks of hydrogen-cooled generator units.
