Gas AnalysisThermal Conductivity Gas Analyzer SR-2050Ex
Introduction
- Principle: The thermal conductivity gas analyzer is an instrument for analyzing gas composition by measuring the change of thermal conductivity of mixed gases. It can be used to measure H2, He and other gases.
- Advantages: The traditional thermal conductivity gas analyzer has many shortcomings in a low range measurement. For example, it cannot detect trace components because the sensor has low detection sensitivity and is greatly affected by background gas. The micro-sensor (MEMS) manufactured by HFSR company features a high precision and integration micro-processing technology that has a high detection accuracy and stable performance.
