Measure gas density rather than thermal conductivity for applications such as hydrogen purity analysis and BTU monitoring in refineries.

Typical GD402 System Configuration Gas Density Analyzer Once again, the global leaders in analytical technology have attained a new level of measurement precision with the EXA-based Gas Density Analyzer. Its innovative cylindrical resonator design enables direct linear measurement of gas density without reliance on thermal conductivity properties. The result is improved accuracy that is unaffected by temperature or secular changes. Driven by a multi-mode oscillation, the GD402 Gas Density Analyzer provides Ϯ1% FS linearity and the total reliability and stability you need to maintain continuous...
