Product Introduction

    DBZX-520The online hydrogen content detection device for internal cooling water tanks is specifically designed for the unique characteristics of hydrogen-cooled generator units' internal cooling water tanks (hydrogen content range 0 to 10% vol). It is an online detection device developed using the thermal conductivity principle to measure hydrogen concentration and hydrogen leakage in internal cooling water tanks. This device not only detects the real-time hydrogen content in the internal cooling water tank but also measures the daily hydrogen leakage and total cumulative flow. Equipped with an embedded microprocessing system, this product is powerful and ideal for detecting hydrogen leakage in internal cooling water tanks.
