Working Principle

The JNYQ-H30 hydrogen analyzer operates on the principle of thermal conductivity measurement. Hydrogen has a thermal conductivity that differs significantly from that of many other gases. The instrument detects changes in heat transfer from a thermal element as the composition of the mixed gas changes.

The measuring circuit converts these changes into an electrical signal. Digital signal processing and temperature compensation are then applied to calculate and output the hydrogen concentration. The analyzer provides a linearized measurement signal for continuous monitoring and connection to compatible control or data acquisition systems.

Note: Measurement accuracy depends on gas composition, calibration, operating conditions, and the presence of other gases that may affect thermal conductivity.
