Product Introduction

    DBZX-520HZ three-in-one hydrogen integrated detection system is an online comprehensive detection system that integrates the detection of hydrogen purity, humidity, and oxygen content in hydrogen-cooled generator units. The system utilizes a German HLP company's constant-temperature micro-thermal conductivity sensor unaffected by ambient temperature, a Finnish Vaisala high-precision, high-stability humidity sensor with self-calibration function, and imported high-precision, long-life trace oxygen sensors, ensuring the accuracy and stability of the detection system, providing strong support for the safe operation of hydrogen systems in hydrogen-cooled generator units.

Features

◆ Uses imported high-end sensors, resistant to oxidative gases, with excellent stability

◆ Automatic conversion between atmospheric and pressurized states, one-key conversion between normal and standard states, no need for manual table lookup and calculation

◆ Unique large true-color touch LCD display, easy to understand and operate

◆ Three-range design, usable with displacement gases CO2 or N2

◆ Independent alarm settings for three ranges, convenient for user displacement operations

◆ On-site user calibration or verification, ensuring reliable instrument use

◆ Features USB data export, on-site software upgrade, and automatic device fault diagnosis

◆ Automatic alarm record saving, storage capacity over 10,000 entries, with historical data traceability

◆ External gas filter and pressure regulator valve, effectively filtering impurities like oil and gas, unaffected by intake pressure fluctuations
