Constant Hydrogen Meter

Product Introduction

The Hydrogen Analyzer is a high-precision instrument designed for real-time and accurate measurement of hydrogen concentration in gases or molten metals. It plays a crucial role in industries such as steelmaking, aluminum processing, vacuum heat treatment, and semiconductor manufacturing, where hydrogen content directly affects product quality, process efficiency, and safety.

Whether measuring dissolved hydrogen in molten steel or monitoring hydrogen levels in protective atmospheres, this analyzer ensures stable, consistent, and actionable data for improved control and reliability.

Product Features

Real-time Monitoring: Provides continuous and fast measurement of hydrogen concentration in gas or liquid phases.

Wide Measurement Range: Capable of detecting hydrogen from trace ppm levels to high-volume concentrations.
