A thermal conductivity hydrogen analyzer gauges the concentration of a target gas inside gas mixtures by measuring the overall thermal conductivity of the mixed gas.
Technical Parameters
| 1 | Measurement Range | 0–0.4%, 0–1%, 0–4%, 0–10% |
| 2 | Repeatability Error | ≤1% |
Working Principle
The core detection logic relies on the distinct thermal conductivity of different gases. Hydrogen has an extremely high thermal conductivity among common gases. When the composition of background gases (such as nitrogen) stays stable, the total thermal conductivity of the mixture varies directly with hydrogen content. The instrument calculates hydrogen concentration accurately by capturing this thermal conductivity difference.
This type of analyzer supports continuous automatic monitoring of hydrogen volume fraction in mixed gas. It features high measurement precision, simple mechanical structure, low maintenance workload and long service life, suitable for non-explosion-proof industrial sites and laboratory research scenarios.
Typical Application Scenarios
| 1 | Power Plants | Hydrogen purity monitoring for generator hydrogen cooling systems, ambient hydrogen concentration detection |
| 2 | Fertilizer Plants | Hydrogen content testing of fresh and circulating gas in synthetic ammonia production |
| 3 | Steel Mills | Hydrogen analysis for purified blast furnace gas after dust removal treatment |
